Haddii aanad waligaa haysan teleefan ama taleefan casriga ah mooyaane, uma badna inaadan maqal kaadhadhka SIM -ka. Iyaga la'aantood, ma isticmaali kartid taleefankaaga inaad wacdo ama aad u dirto fariimaha qoraalka ah dadka. Waxaa laga yaabaa inaad tan garanayso, laakiin ma garanaysaa waxa SIM Card-ku yahay iyo sababta aad mid uga baahan tahay? Ma qabtaa hubanti la'aan ku saabsan waxa kaararka SIM loo isticmaalo, ama macluumaadka ku kaydsan SIM kaarka? Haddii aad rabto inaad ogaato jawaabaha su'aalahan iyo kuwo kale, akhri maqaalkan oo ogow:

Waa maxay SIM-kadh?

SIM waa soo gaabinta loogu talagalay Macmiilka Aqoonsiga Module^{(Subscriber Identity Module)} ama Module Aqoonsiga Macmiilka^{(Subscriber Identification Module)} . Kaadhadhka SIM^(SIM) -ku waa kaarar fidsan oo yar yar oo ka kooban wareegyo isku dhafan oo ay isticmaalaan shirkadaha telefoonku si ay u aqoonsadaan oo ay u xaqiijiyaan ka-qaybgalkaaga shabakadahooda. Si kale haddii loo dhigo, SIM Cards waa waxyaalaha yaryar ee u oggolaanaya hawl-wadeennada mobiladu inay ogaadaan lambarka taleefankaagu waxa uu yahay iyo qorshooyinka codka iyo xogta ee aad ku biirtay oo aad lacag ku bixinayso.

Waxaa jira laba nooc oo waaweyn oo shabakadaha mobilada ah: GSM iyo CDMA . GSM- ku waxa uu ka yimaadaa Global System for Mobile, talefannada isticmaalana waxa ay had iyo jeer u baahan yihiin isticmaalka SIM Card-ka. Taleefannada CDMA^(CDMA) , dhinaca kale, uma baahnayn SIM kaar si uu u shaqeeyo waagii hore, laakiin telefoonada CDMA ee cusub ayaa iyaguna u baahan mid.

Waa maxay kaarka SIM- ka loo isticmaalo? Kaarka SIM-^(SIM) ku muxuu qabtaa?

Kaadhadhka SIM^(SIM) -ka ayaa iyaga ku haya macluumaadka muhiimka ah, oo ay adeegsadaan sidayaasha mobiladu si ay u ogaadaan aqoonsigaaga oo ay awood ugu yeeshaan in ay ku caddeeyaan taleefankaaga shabakadahooda. Malaha xogta ugu muhiimsan ee lagu kaydiyo SIM- kaarka waa:

• Mobile Country Code (MCC) iyo Mobile Network Code (MNC) waa kood gaar ah oo u sheega shabakadaha mobaylada ee uu talefankaagu ku xidho waddanka uu ka tirsan yahay SIM- kagaga
• Lambarka Aqoonsiga Macmiilka Mobilka (MSIN)^{(Mobile Subscriber Identification Number (MSIN))} waa kood ay adeegsadaan sidayaasha wireless-ku si ay u aqoonsadaan taleefankaaga si uu ugu xidho lambarka taleefankaaga iyo rukunsiga taleefankaaga.
• Furaha Xaqiijinta^{(Authentication Key)} waa qiime gaar ah oo 128-bit ah oo uu SIM kaarkaaga u qoondeeyay xiriiriyahaaga moobiilka, oo loo isticmaalo in lagu siiyo marin u helka shabakada side. Furahani waxa uu ku kaydsan yahay kaarka SIM- ka iyo xog-ururinta shabakada labadaba.

Intaa waxaa dheer, inta badan kaararka SIM-ka sidoo kale waxaa loo isticmaali karaa kaydinta qaar ka mid ah xogtaada shakhsi ahaaneed, maadaama ay sidoo kale hayn karaan:

• Xidhiidhada (Buugga Taleefanka): Kaadhadhka ^{(Contacts (Phone book):)}SIM- ka badankoodu waxa ay kaydin karaan tiro xidhiidho ah. Kaararka SIM^(SIM) -ka ee casriga ah, xadka badiyaa waa 250 xiriiriye.
• Fariimaha SMS (Farriimaha qoraalka): ^{(SMS messages (Text messages):)} SIM- kaadhadhku waxa kale oo ay hayn karaan farriimaha SMS -ka ee aad hesho. Si kastaba ha ahaatee, tirada fariimaha ay kaydin karaan ayaa aad uga hooseeya tirada xiriirada. Caadi ahaan, kaadhadhka SIM -ku waxa ay kaydin karaan ilaa 32 fariimo SMS ah.

Isla sidaas oo kale, tirada gelitaanka buugga talefanka iyo farriimaha SMS -ka ee ^(SMS)SIM- kaarku hayn karo way kala duwan yihiin iyadoo ku xidhan inta ay leeg tahay kaydka kaydinta (memory) uu leeyahay. Qadarka awoodda kaydinta ee laga heli karo kaarka SIM- ku way kala duwan tahay hadba waxa qaadaha gacanta ee soo saaray SIM- kaas uu go'aansaday. Inta badan, kaadhadhka SIM -ka waxay leeyihiin ilaa 128 kilobytes oo xusuusta ah. Kaas oo noo keenaya su'aasha xigta:

SIM-kadhku ma kaadhka xusuusta?

Maya, iyo Haa^(Yes) . Kaarka SIM-^{(A SIM)} ku waa kaadhka xusuusta been abuurka ah, maadaama uu waxoogaa xusuus ah ku leeyahay gudaha. Si kastaba ha ahaatee, sida aad hadda ogtahay, xusuustaas waxaa loo isticmaalaa kaydinta tiro xaddidan oo ah xiriirada buugaagta taleefanka iyo fariimaha SMS^(SMS) -ka . Xusuusta ku jirta SIM kaarka looma isticmaali karo in lagu keydiyo sawiro, muuqaalo, muusig, dukumeenti, ama nooc kasta oo fayl ah. Markaa, in kasta oo aad odhan karto kaarka SIM- ku farsamo ahaan waa kaadhka xusuusta, laakiin nolosha dhabta ah, uma isticmaali kartid kaadhka xusuusta caadiga ah sida kaarka SD^{(memory card such as an SD card)} .

Waa maxay noocyada kala duwan ee kaararka SIM ?

Dhammaan kaadhadhka SIM- ka waxay sameeyaan wax isku mid ah waxayna leeyihiin nooc isku mid ah chips (wareegga isku dhafan) iyaga. Si kastaba ha ahaatee, kaadhadhka SIM -ku waxay yeelan karaan qaabab iyo cabbirro kala duwan, kuwaas oo u dhigma noocyada kala duwan ee boosaska SIM ee laga helo telefoonada. Kuwani waa qaababka SIM- kaarka maanta la isticmaalo:

• SIM-ka-buuxa^{(Full-size SIM)} ayaa la soo bandhigay 1991 wuxuuna leeyahay dherer 85.6 mm (3.37 in), balac 53.98 mm (2.125 in), dhumucdiisuna waa 0.76 mm (0.030 in).
• Mini-SIM wuxuu soo muuqday markii ugu horeysay 1996 - cabbirkeedu waa 25 mm (0.98 in) × 15 mm (0.59 in) × 0.76 mm (0.030 in).
• Micro-SIM waxaa la bilaabay 2003 waana 15 mm (0.59 in) oo dherer ah, 12 mm (0.47 in) ballac ah, iyo 0.76 mm (0.030 in) dhumucdiisuna tahay.
• Nano-SIM waxa uu soo baxay 2012-kii oo hadda waa kaarka ^(Nano-SIM)SIM- ka ee inta badan la isticmaalo . Taasi waa inta badan sababtoo ah kuwa soo saara taleefannada casriga ah waxay door bidaan cabbirkooda yaryar, kuwaas oo aan meel badan ka qaadin taleefannada casriga ah ee horeyba loogu cidhiidhi lahaa wareegyada isku dhafan, kamaradaha, iyo kuwa kale. Nano -SIM- yada waxay leeyihiin dherer 12.3 mm (0.48 in), 8.8 mm (0.35 in) ballac ah, iyo 0.67 mm (0.026 in) oo dhumucdiisuna tahay.
• eSIM waa nooc gaar ah oo SIM kaar ah oo la yiraahdo Embedded-SIM oo la bilaabay 2010. eSIM^(eSIMs) -yada waxaa si toos ah loogu iibiyaa talefannada, markaa kama soo bixi kartid oo uma wareejin kartid taleefan kale. Waxaa jira oo kaliya dhowr taleefannada casriga ah ee taageera kaararka eSIM^{(eSIM cards)} , sida caadiga ah qalabyada sare ee Google ( Pixel 4 iyo 4XL ), Apple (iPhone 11, iPhone 11, 11 Pro , 11 Pro Max , iPhone XS, XS Max , iPhone XR ), Samsung ( Galaxy Fold , S20 , S20+ , S20 Ultra ,Z Flip ).

Telefoonku ma shaqayn karaa kaar la'aanteed ?^(SIM)

Su'aal sharci ah: Miyaad isticmaali kartaa teleefan haddii uusan lahayn SIM-kaarka? ^{(Can you use a phone if it doesn't have a SIM card?)}Jawaabtu waa haa iyo maya labadaba. Haddii taleefankaagu ka shaqeeyo shabakad CDMA ah, sida kuwa ka yimid Mareykanka ^(United) ' ^(States)Sprint ama Verizon , haa, waxaad isticmaali kartaa taleefankaaga SIM kaar la'aan. Si kastaba ha noqotee, xitaa shabakadaha noocan oo kale ah, waxaad u baahan tahay SIM kaarka haddii aad rabto inaad awood u yeelato inaad ku xirto 4G LTE sababtoo ah heerkani wuxuu u baahan yahay kaararka SIM . Haddii sidahaga moobiilku isticmaalo shabakadaha GSM , markaa jawaabtu sax maaha bilawgii, maadaama GSM uu u baahan yahay SIM- kaarka si kastaba ha ahaatee.

Haddii aad la yaabban tahay inaad talefanka ama casriga ah u isticmaali karto waxyaabo kale oo uu samayn karo marka laga reebo samaynta ama helista talefannada ama fariimaha qoraalka ah, jawaabtu waa haa. Waxaad u isticmaali kartaa talefan kasta ama casriga ah inaad ku ciyaarto, ku ciyaarto, ama ku socodsiiso apps ka dusheeda, adigoon haysan SIM card.

Maxaa dhacaya haddii aad SIM kaarkaaga la baxdo oo aad geliso taleefan kale?

Marka aad SIM kaarka ka saartid taleefankaaga, kuma xidhi karo sidahaaga moobilka. Si kale haddii loo dhigo, kama heli kartid ama ma wici kartid, mana diri kartid mana heli kartid farriimaha SMS -ka . Markaad SIM kaarka geliso talefan kale, talefankaas wuxuu isticmaalayaa SIM- ka si uu isu diiwaan geliyo talefankaaga gacanta. Kadib, waxaad isticmaali kartaa taleefanka cusub wicitaanada iyo fariimaha. Sidoo kale, haddii aad leedahay xiriirada ama fariimaha SMS^(SMS) ee ku kaydsan SIM kaarka, waxay noqon diyaar on telefoonka cusub. Isla markaana, lagama heli karo kii hore.

Waxa muhiim ah in la xasuusto ku wareejinta SIM- kaarka talefannada waa in talefanka cusub ee aad gelinayso SIM-^(SIM) ka aan laga xannibin isticmaalkiisa. Qaar ka mid ah hawl-wadeennada mobiladu waxay iibiyaan taleefannada iyo talefannada casriga ah ee ku xidhan shabakadahooda. Xaaladahan oo kale, waxaa laga yaabaa in kaadhka SIM- kaagu aanu ku shaqayn talefanka cusub ilaa aad ka furto. Si aad u furto talefan/taleefanka casriga ah, waxa ay u badantahay in aad la xidhiidho shirkada moobaylka ee kaa iibisay, waxana laga yaabaa in habka furista ay ku baxdo lacag.

Ma ku isticmaali kartaa laba SIM- kaadh isla taleefoonka?

Haa, taleefanno badan oo casriga ah iyo xitaa taleefannada "doqon-la'aanta" ee la iibiyay maalmahan waxay isticmaali karaan laba SIM- card oo kala duwan isku mar. Aaladahaan waxaa loo yaqaan Dual SIM phones, waxayna isticmaali karaan hal ama labada SIM- card ee aad geliso si aad u bilowdo ama lagu helo wicitaano taleefan. Haddii aad rabto sharaxaad faahfaahsan waxa Dual SIM yahay iyo sida uu u shaqeeyo, akhri Dual SIM - waa maxay? Waa maxay macnaha Dual SIM? Sidee Dual SIM u shaqeeyaa? ^{(Dual SIM - What is it? What does Dual SIM mean? How does Dual SIM work?)}.

Ma qabtaa su'aalo kale oo ku saabsan kaararka SIM -ka iyo waxa ay qabtaan?

Waxaan rajeyneynaa inaan ku guuleysanay inaan jawaabo cad ka bixinno su'aalahaaga ku saabsan kaararka SIM -ka. Ma jiraan wax kale oo aad rabto inaad ka ogaato kaararka SIM -ka ama waxa loo isticmaalo?

What is a SIM card & What does it do?

Unless you've never had a phone or a smartphone, it is unlikely that you haven't heard about SIM cards. Without them, you can't use your phone to call or send text messages to peoрle. You might know this, but do you know what a SIM card is and why you need one? Do you have unсertainties regarding what SIM cards are used for, or what informatіon is stored on a SIM cаrd? Іf you want to know the anѕwers to these questiоns and mоrе, read this artiсle and fіnd out:

What is a SIM card?

SIM is an acronym for Subscriber Identity Module or Subscriber Identification Module. SIM cards are small flat cards that contain integrated circuits used by phone companies to identify and authenticate your subscription on their networks. In other words, SIM cards are those small things that allow mobile operators to know what your phone number is and what voice and data plans you're subscribed to and paying for.

There are two major types of mobile networks out there: GSM and CDMA. GSM comes from Global System for Mobile, and phones that use it always require the use of a SIM card. CDMA phones, on the other hand, did not require a SIM card to work in the past, but newer CDMA phones need one too.

What is a SIM card used for? What does a SIM card do?

SIM cards hold essential information on them, used by the mobile carriers to know your identity and be able to authenticate your phone on their networks. Probably the most important data stored on a SIM card are:

• Mobile Country Code (MCC) and Mobile Network Code (MNC) are unique codes that tell the mobile networks to which your phone connects what country your SIM card (and phone subscription) belongs to.
• Mobile Subscriber Identification Number (MSIN) is a code that's used by the wireless carriers to identify your phone so that it can link it to your phone number and phone subscription.
• Authentication Key is a unique 128-bit value assigned to your SIM card by your mobile operator, used for granting you access to the carrier's network. This key is stored both on the SIM card and on the network carrier database.

Furthermore, most SIM cards can also be used for storing some of your personal data, as they can also hold:

• Contacts (Phone book): Most SIM cards can store a number of contacts. On modern SIM cards, the limit is usually 250 contacts.
• SMS messages (Text messages): SIM cards can also hold SMS messages that you receive. However, the number of messages they can save is much lower than the number of contacts. Typically, SIM cards can store about 32 SMS messages.

On that same note, the number of phone book entries and SMS messages that a SIM card can hold differs depending on how much storage space (memory) it has. The amount of storage capacity available on a SIM card varies according to what the mobile carrier that issued that SIM decided. In most cases, SIM cards have up to 128 kilobytes of memory on them. Which brings us to the next question:

Is a SIM card a memory card?

No, and Yes. A SIM card is a pseudo-memory card, as it does have some memory inside. However, as you know now, that memory is used for storing a limited number of phone book contacts and SMS messages. The memory on a SIM card cannot be used for saving photos, videos, music, documents, or any other type of file. So, although you could say that a SIM card is technically a memory card, in real-life, you cannot use it as a typical memory card such as an SD card.

What are the different types of SIM cards?

All SIM cards do the same thing and have the same kind of chips (integrated circuit) on them. However, SIM cards can have different formats and dimensions, matching the various types of SIM slots found on phones. These are the SIM card formats used today:

• Full-size SIM was introduced in 1991 and has a length of 85.6 mm (3.37 in), a width of 53.98 mm (2.125 in), and a thickness of 0.76 mm (0.030 in).
• Mini-SIM appeared for the first time in 1996 - its dimensions are 25 mm (0.98 in) × 15 mm (0.59 in) × 0.76 mm (0.030 in).
• Micro-SIM was launched in 2003 and is 15 mm (0.59 in) in length, 12 mm (0.47 in) in width, and 0.76 mm (0.030 in) in thickness.
• Nano-SIM came into existence in 2012 and is now the most commonly used type of SIM card. That's mainly because smartphone manufacturers prefer its smaller dimensions, which don't take a lot of space in the smartphones already crammed with integrated circuits, cameras, and others. Nano-SIMs have a length of 12.3 mm (0.48 in), 8.8 mm (0.35 in) in width, and 0.67 mm (0.026 in) in thickness.
• eSIM is a special type of SIM card called Embedded-SIM that was launched in 2010. eSIMs are soldered directly inside phones, so you can't take it out and move it to another phone. There are only a few smartphones out there that support eSIM cards, typically higher-end devices from Google (Pixel 4 and 4XL), Apple (iPhone 11, iPhone 11, 11 Pro, 11 Pro Max, iPhone XS, XS Max, iPhone XR), Samsung (Galaxy Fold, S20, S20+, S20 Ultra, Z Flip).

Can a phone work without a SIM card?

A legitimate question: Can you use a phone if it doesn't have a SIM card? The answer is both yes and no. If your phone works on a CDMA network, like those from United States' Sprint or Verizon, yes, you can use your phone without a SIM card. However, even on such networks, you need a SIM card if you want to be able to connect to 4G LTE because this standard requires SIM cards. If your mobile carrier uses GSM networks, then the answer is no right from the start, as GSM requires SIM cards no matter what.

If you are wondering whether you can use a phone or smartphone for other things it can do besides making or receiving phone calls or text messages, the answer is yes. You can use any phone or smartphone for playing, gaming, or running apps on it, without having a SIM card.

What happens if you take out your SIM card and put it in another phone?

When you take the SIM card out of your phone, it can no longer connect to your mobile carrier. In other words, you can't receive or make calls from it, nor send or receive SMS messages. When you insert the SIM card into another phone, that phone uses the SIM to register to your mobile operator. Then, you can use the new phone for calls and messages. Also, if you have contacts or SMS messages stored on the SIM card, they become available on the new phone. At the same time, they're no longer accessible from the old one.

What's important to remember about moving SIM cards between phones is that the new phone in which you're inserting your SIM must not be blocked from using it. Some mobile operators sell phones and smartphones that are locked into their networks. In such cases, your SIM card might not work on the new phone until you unlock it. To unlock a phone/smartphone, you'll probably have to contact the mobile company that sold it to you, and the unlock procedure might cost some money.

Can you use two SIM cards in the same phone?

Yes, many smartphones and even "dumb" phones sold these days can use two different SIM cards simultaneously. These devices are called Dual SIM phones, and they can use one or both SIM cards you insert in them to initiate or to receive phone calls. If you want a detailed explanation of what Dual SIM is and how it works, read Dual SIM - What is it? What does Dual SIM mean? How does Dual SIM work?.
