Yes you can. Tmobile an AT&T both run on a GMS frquency.

Mymalathy answer:

You need to unlock from AT&T Network lock,then you can use the T-Mobile Network,You can use the unlock code to unlock it... after unlock it use your phone with any GSM Network Sim card..

Yes the iphone 4 uses whats called a micro sim card it is smaller then the regular sim card out there. At www. phonetraderonline.com they can custom cut your existing sim card or provide you with a micro sim for your carrier.

As the Bose 321 has its own universal remote, it is unlikely that a code-based remote would operate all of the functions. It would be easier to use the Bose remote program the functions of the TV and other units. If you have lost your Bose remote, it is likely that only an advanced remote, such as the Logitech Harmony series would be able to replace it.

AT&T U-verse remote control codes for INSIGNIA HDTVs (mine is a NS-24E730A12 and I have a black remote control) are: 1034, 1035, 1040, 1398, & 1465.

sorry to say... I kinda still cost because it is far away and stuff but wait a sec,What cell copany does your friend from far away have? And is t-mobile to t-mobile FREE? if it is you can call during anytime of the day! Free nights and weekends does not include International Calls.

Yes, just take it out of the old phone and place it in the new one.

If your old sim card is deactive because you were given a new one with the same phone number, there is no way to activate the old sim card - not in Australia anyway

Yes yes yes yes! It is the coolest phone....eva! It really depends is your willing to pay the money for this phone....a lot! But I am telling you, it's worth every penny! This phone is really for teenagers and adults, but if you want you could give it to children. I am 16 years old and trust me, it's awesome. .....the phone does get a little old tho im tired of mine....great phone just glitchy and un reliabe

They can go back as they want - limited only by how far the carrier keeps them on file, carriers usually store them for 1 year and there is no legal requirement for them to be stored longer. So even if they kept them longer they are not stupid enough to divulge that to random police people who can directly publicize these matters as they aren't bound to keep phone company secrets.

Even though these networks are not compatible, there is a way to transfer the contacts, check out http://sim-reader.com.

The program is called SIM Manager, it is compatible with all types of SIM cards - 2G, 3G, R-UIM and Nextel. Once you read the data from one card, you can write it to any other supported card type.

Note that a Nextel phonebook entry has many properties (name, number, mobile number, email, etc), while GSM cards only have a name and a number - so naturally, some of your Nextel entries will be mapped to more than one GSM phonebook entries.

I have been wondering this same question also. With my broken att goPhone I transferred the sim to a working RAZR v3 and an ATT Tilt. Niether of them worked as they both said no service. So the answer is NO.

You should be able to if the phones are from the same network/phone company and based on the same technology. (Size for instance) Although you will need to add the serial number to the phone companies records so that the sim will co-operate with the towers and authenticate you. Once added, all you have to do is call in and let them know you are using the other phone and they will switch you in an instant. Then you call back to let them know you switched back. On the action of switching, call first if you are using the cell phone to make the change. You should not get disconnected from the network until the call is terminated. Then you switch the sims. Try to make a call. After you have successfully placed a call, you are now ready to receive a call. It may take a few minutes before you can make a call. It used to be that you could not receive a call until you place one. It may be different on your network.

Only if the phone is not locked to t-mobile.

Steve Buscemi is the Dad.....Norm McDonald is the son

Take the phone back, you cannot get it to work if the sim is not registered.

That depends. Modern "World Phones", hybrid phones like the iPhone 4S that contain both a CDMA radio and GSM radio are technically possible, though Verizon won't activate any iPhone not purchased from them, since Verizon iPhones are "white listed" to the network and sim locked to prevent using them on domestic GSM carriers. On the other hand, you can take a "World Phone" such as a Blackberry from Verizon and use it with an AT&T SIM card, as long as it is SIM unlocked, chances are you will only use the GPRS network since most Blackberrys on Verizon were limited to that. Newer Verizon Blackberrys like the 9830 have modern GSM radios to handle more.

If this happens repeatedly, the one friend with the Verizon Wireless phone that is having problems receiving needs to check their account to make sure it is provisioned correctly and update their phone by dialing *228 SEND option 2. If still having trouble, this friend needs to have their phone looked at.

What network does sprint use? I know Verizon uses cdma network

Look at the top edge of the iphone 3g. there is a long button, and a headphone hole. See the tiny hole between the two? stick a small object, such as the little pick that comes with it, in the hole, and the sim card holder will pop out.

no u cant but if u chip your vodephone phone u can

Actually yes ! I used to work with a guy whoo is blind. His phone dictates his text messages (both sent and received) to him via the loudspeaker. There is specialist software available for this function.

Land line phones that receive a text message, even if it is sent in error, will dictate the message to whomever answers the phone as well.

Unlocking your Motorola phone can offer you the flexibility to switch carriers or use different SIM cards, both domestically and internationally. Here's how you can get a free code to unlock your Motorola phone:

Steps to Get a Free Unlock Code:

1. Contact Your Carrier: The first step is to contact your current service provider. Many carriers offer free unlock codes if you meet certain criteria, such as being a customer for a specific period.
2. IMEI Number: You'll need your phone's IMEI number, which can be found by dialing *#06# on your phone. This unique identifier is required to generate an unlock code.
3. Submit Request: Once you have the IMEI number, submit an unlock request to your carrier. They will provide you with a code if you meet their requirements.
4. Third-Party Services: If your carrier is unable to provide a free code, you can also look for third-party websites that offer free unlock codes. However, be cautious and ensure the site is reputable.
5. Software Methods: Some software solutions can also unlock your phone for free. However, this method is generally not recommended unless you are tech-savvy and aware of the risks involved.
6. Enter the Code: Once you have the unlock code, insert a SIM card from a different carrier and enter the code when prompted. Your phone should now be unlocked.

It depends on the phone model, the sim card it has, and whether it needs to be and has been unlocked. Even if the technical issues are avoided, there is the possibility that a vendor will not allow a phone model not approved to join its network based on its serial number or ESSID. Contacting customer support may help if you reach someone symphatic or not aware of the restriction.
