I have 9 months left on my t-mobile contract and I'm content with their service. The problem is I want a phone that another carrier has that is not offered by t-mobile. Can I use my sim card with their phone if I purchase an unlocked phone of that type and still have the same service and regular cell phone functions that I have now.

Sure, the unlocked phone can work well with your pre-paid SIM card, but you should make sure the phone supports GSM900/1800/1900MHz which is required by the SIM card of T-Mobile.

I have an unlocked at&t tilt aka kaiser Htc tynn. My question concerns how do I get T-mobile software on and At&t software off?
I am trying to sell this phone and it's confusing to potential buyers. From T-mobile when they place their sims in and it still shows at&t software it is unlocked because otherwise it would ask for PUK a code or message insert sim card.
I unlocked it myself when contract was up requested and received the PUK code used old t-mobile sim card. Any information would be appreciated. Thanks

That indicates the phone is not really unlocked, and it can not work suitably with pre-paid SIM cards.

Once a cell phone is unlocked would I still have to pay for extras like GPS and Web access? Or is all this unlocked to me? If not, how can I get all this for a low cost?

I was thinking about buying a unlocked phone, but i do not know if it will work with US Cellular? If any one could answer my question that would be great.

Answered by onThesource.com(ONLY for reference)
We can not locate the concrete network frequency of US Cellular. We suggest you buy those UNLOCKED phones which support 850/1900 simultaneously, namely, quad band cell phones.

Please make sure whether this phone is a contract phone or unlocked phone, if for the former, you can not activate it, if for the latter, needless to activate.

so, will an unlocked phone work with a Net10 or TracFone SIM card?

Answered by onThesource.com(ONLY for reference)
Sure, it will.

Posted by: anon23853
hey, for all you guys that are asking if the unlocked phone will work with your SIM card, look up the phone you want on ebay (there are tons of unlocked phones there) and read the description. it should tell you which SIM cards it works with and answer any other questions you have.

Answered by onThesource.com(ONLY for reference)
Unlocked phones are opposite to contract phones, but do not mean they can work in any phone carriers, as you know, different phone carriers need different network frequencies.

I plan on buying a phone as a gift and I know my friend uses ATT and still has a year under the existing contract. I was wondering what my safest bet was? I would hate to get a phone that couldn't be used!

Buy one unlocked quad band phone, and put the SIM card into the new phone, just go there.

thank you soooo much for this... i didnt quite understand the concept but now i do...i have a question though... if unlocked means they can read any sim card that's inserted in the phone... does it mean that i can insert sim cards from any country; because i live in panama, latin america and i travel to the U.S and a lot and i was wondering if i could just buy one of these phones and buy a sim card of an american carrier and use it when i'm there and when i get back use my regular sim card??

Answered by onThesource.com(ONLY for reference)

I am trying to get the sim card out of a Samsung SCH-U340 ... pretend you are speaking to a child and explain how to get to the card ... is it under the battery, do you have to unscrew the phone to get to it? Thanks!

Answered by onThesource.com(ONLY for reference)
Sure, it is a simple question.

This article is very helpful. I am just looking into the concept of unlocked cell phones. I am learning about SIM cards and the different networks GSM and CDMA. There is one thing I do not understand. If I purchase the unlocked cell phone I want and insert the SIM card, am I good to go? Do I have to sign with or notify any company? Is there a next step I am missing? Thanks so much.

Answered by onThesource.com(ONLY for reference)
What you are required to do it to put the old SIM card into the new unlocked phone.
