What does GSM unlocked mean. I am replacing the same phone ATT is my carrier. I am assuming I can plug my current sim card in and it will work.

As an unlocked phone it is capable of working with any GSM Carrier providing their services using a SIM Card. However, we can only guarantee basic call and text, we recommend contacting your Carrier and making sure they provide their services to this model phone without any restrictions. Unlocked cell phones are compatible with GSM carriers like AT&T and T-Mobile as well as with GSM SIM cards (e.g. H20 and select prepaid carriers). Unlocked cell phones will not work with CDMA Carriers like Sprint, Verizon, Boost or Virgin.

IF you are a current att customer on GSM, as I am, all I had to do was stick in the old sim and turn it on. The quad band capability does a "searching" for service. After a second it finds ATT and hooks up. Good luck, it is a pretty good phone, and mine has withstood a couple of drops to blacktop.

It means you can use it with any carrier. Normally it works for non US customers that will need to contract local internet. If you dont know which internet provider you are going to use, or you travel a lot, its better to have an unlocked device and not depend on a contract with AT&Tor; Sprint or Verizon etc.

Unlocked means you can use a SIM card from any carrier. A locked one is tied to an specific carrier. Regardless locked or unlocked they do have a SIM card slot

The SIM card will work from one phone to the other, I have used my same SIM card in AT&T; contract phones, Go Phones and unlocked non-AT&T; phones. I don't think AT&T; knows or cares much what phone you use the card in but my default answer would be that you need to ask them to be sure. That said if you have an active AT&T; SIM card I think it would work the same as your current plan.

Its a phone from a company (ex: Att) that uses sim cards and, after unlocked, you can use it with a diferent company. (Ex: tmobile, or any other)

How does an unlocked phone work. I have ATT and have no contract. Will this phone work?

Yes GSM - AT&T; phone. Will need to buy new sim upon receiving. Then won't be locked into contact.

I think it's unlocked Gsm, so it depends on what carriers you have. I think it's T-Mobile and at&t.;

It means you need to get a working sim card. These phones come unlocked & you have to put your own sim card in it. Mine didn't come with a sim card. I took my sim out of my working phone & put it in that phone. Hope that helps.

If you have a second line with a sim card that is active. My wife dropped her phone in the sink with the dishes and it is now clean and dead. I got the att r225 and put her sim card in and now she has service again. My wife and I do not use smart phones. We only use the old GSM service,to make calls and text. I got an unlocked R225 and now it works on AT&T; or the bring your old phone Cricket network with no contract.

Normally this is because the phone is not unlocked. Provisioned meaning to set up a line or network for a customer. This is an industry term used by the telephone companies. Put the same sim on another gsm phone, make a call using the sim. If this works. You know it's the phone. Sometimes turning the phones airplane mode on and off after installing the card works too.

An unlocked phone, is a phone that will let you use any sim card on it. Like any company, net10, h2o, simple mobile, t mobile, at&t;, sprint, etc........ So just get any sim card you want on any company and it work fine

It means it is at mobile phone that can accept a SIM chip from another phone company Now before you go out and just purchase a phone you need to make sure you know which frequency your company is on, the only thing I do know is T Mobile is GSM
