Unlocked Cell Phones means that the phone is not locked to any particular GSM phone service providers. Before you make a decision to purchase a particular phone, please make sure that the frequency of your mobile phone network is compatible with the phone you wish to purchase.
If the network is compatible, simcards provided from your GSM service provider (at&t, T-Mobile, Roger Wireless, etc) will work with the phone.
Within the United States and Canada, the majority uses only GSM 1900/ GSM 850 bandwidth. In UK, Australia and most parts of Asia with the exception of Japan and South Korea, their networks use GSM 900 / GSM 1800.
Here are the country's ranges for your reference:
Quad Band GSM 850/900/1800/1900 WCDMA
Europe, Asia, Africa, North America, South America, New Zealand and Australia
Tri band GSM 900/1800/1900 +UMTS
Europe, Asia, Africa, North America, South America, Australia, and New Zealand

if its from atnt or a gsm carrier that uses sim cards
wireless carriers such as Verizon work on the cdma network and do not have sim cards in any of their phones or devices
Not true...I have a Verizon Motorola Droid phone and it most assuredly has a SIM card. So the above is incorrect.
Well if you want to text or call or use the internet yes..
cdma uses a different system, but same idea.
If you want to use device as media player, then no
basically it doesbt require one, but it is recommended
The SIM card in phones is based off the company that produces their cell phones. There are two companies in the United states that are contract phones and they have sim cards they are AT&T and T-mobile. Sprint and Verzion do not have SIM cards.
Yes. Most modern cellphones have SIM cards though they are not interchangeable.
All phones except CDMA (i.e. Verizon) phones use SIM cards.
Hi. My name is Sam. No, CDMA do not use SIM cards, just GSM :)
No, right now only T-Mobile and AT&T use SIM cards.
all android PHONES have an entry for SIM cards. not all ANDROID devices have SIM card entries though, eg. tablets, Samsung Galaxy Camera etc.
There is no such thing as a CDMA SIM card, since CDMA phones do not use SIM cards.
Nope, Verizion and Sprint are CDMA signal providers. They do not use SIM card. GSM phones do such as AT&T and T-Mobile.
No, You cannot use reliance CDMA sim card (or) any other CDMA card sim card on Apple iphone 4s. Any GSM Sim card will work on factory unlocked Apple iphone 4s but not CDMA sim ONLY IN INDIA.
Cricket Communications uses CDMA, so their phones do not have SIM cards.
no. [Edit by Eduardo] This phone does not take a SIM card because this is a CDMA phone. Like most other Android powered CDMA phones, they don't take SIM cards. This is because they activate using another way, using and IEMI to activate. *With the exception of the later Galaxy S 2 and 3 phones, because CDMA carriers HAVE to provide a SIM card for those phones.
Virgin Mobile uses CDMA, so their phones do not take SIM cards.
No, it only needs one SIM card. The Blackberry Storm2 9550 is both CDMA and GSM, and CDMA phones do not use SIM cards. So you would only need to use one SIM card when you switch the phone's mode to GSM.
US Cellular uses CDMA technology, not GSM, so, their phones do not use SIM cards.
Nope, cause metropcs does not use sim cards but a esn number. Sim cards are usually associated only with GSM phones, and metropcs Verizon and sprint all use CDMA
The full form of SIM is Subscriber's Identity Module. The SIM card is used into mobile phones to make calls, send messages, use internet. There are two types of SIM card. One is GSM and another is CDMA. The full form of GSM is Global System for Mobile communication. The full form of CDMA is Code Division Multiple Access. The CDMA Technology is superior than GSM.
No. Since it is a CDMA phone, it does not use a SIM Card.
No you cannot. CDMA phones do not accept SIM cards.
