SIM cards have generic sizes and basic functions. The difference lie in the frequencies that they operate on.
yes they do all have sim cards also on a different note the t-mobile phones accepts the cingular sim cards when unlocked and vice versa
Not all cell phones are compatible with SIM cards. Some only work with a contract, and you need to unlock the phone before you can use a SIM card.
No it will not fit, the micro one is smaller than the regular sim card.
Cellphones usually have a SIM card. There are land lines that do not as well as Satellite phones also do not have SIM cards.
yea i have gotten several phones from att and used the same sim card for all of them, and kept the same phone number.
Cellcom in Wisconsin does not have sim cards, wish they did. I have heard that you can get a sim card from them but non of their phones have a spot for sim cards.
No, the T-Mobile sim cards don't fit in AT&T phones and AT&T phone sim cards dont fit in T-Mobile phone. And when I say fit they fit in the slot they just dont read the information from different users.
"Yes. All phones need a SIM card, or it will not function." Actually, that answer is incredibly wrong. SOME phones use SIM cards. Some phones don't. A phone on the Verizon, Alltel, or Sprint networks do not use SIM cards as they operate on CDMA platforms. iDEN (an ancient Nextel system) or the global standard GSM (AT&T) use SIM cards.
No most phone companies do not allow any SIM card to go into all phones. The only exception I have found is the SIM cards for ATT phones and TMobile phones.
ALL mobile phones have a SIM CARD - It's what distinguishes the individual identity of the phone.
Well . There are two major mobile carriers. One is called China Mobile, and cell phones with their service usually use sim cards. And the other one is called China Unicom, and they are using CDMA which does not use sim cards.
There is no sim card in Verizon, Sprint, or Alltel phones. The reason is that they operate on CDMA technology which does not require sim cards.
