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.
Yes you can. The contract relates to the phone number - not the handset. So long as the new handset is on the same network - or has been unlocked - you can simply put your existing SIM card in the new phone.
It is up to you. A contract means you can get the phone for free, and get a new one when the contract renews. Non contract is when you have to buy the phone up front and put a PAYG sim in it
YES; as long as the SIM works in that phone.
Yes you can. . . .for example you can put a at&t prepaid go phone SIM into an at&t contract phone and it will still be prepaid.
Yes. It must be from the same carrier, though. For example, an AT&T sim only works in an AT&T pay-as-you-go, not a VirginMobil or Sprint.
Yes you can. I have an AT&T go phone and all I did was put my sim card in the phone. No need to start a new line.
If the net 10 phone is "unlocked" and the sim card fits. Usually the phone needs to be unlocked network wise not pin wise.
A phone SIM card is built to an industrial standard, they will fit and work in any phone manufactured by any manufacturer - they all have and provide standard SIM card connectors. However, some Mobile Phone companies who "give" you a free phone as part of a contract deal with, them LOCK the phone to their service (in software in the phone), which means that that phone will only work with a SIM card provided to you by them. It is possible to get the phone "unlocked" or to purchase a "SIM free" phone which then allows you to use any SIM in the phone.
I dont think so only if the payg sim is the same network as the contract sim
Yes. You can also put a contract SIM into a pre-paid phone.
It Just Finishes and that's it. But You still can keep the phone. The sim has nothing on it.
It will, but only if the pay as you go SIM card actually works in the phone. Most phones these days tend to get locked to the network they were provided with, and sometimes even locked to the particular SIM they were provided with. Obviously, even if it does work OK, the monthly SIM will still need to be cancelled if you don't wish to continue paying for it.
You can get a "Simplicity Sim" from o2, which says there is no contract, but you can keep your number and phone. It is kind of like a pay monthly deal, except you can choose any phone to put the sim card and you can choose to pay for 1 month or 12 months at a time.
