If you're talking about a 'pay as you go' phone - no. If you mean a contract phone - yes !
No, you don't need a contract. You can get a pre-paid phone which means no contract/monthly phone bill, but it depends what you mean by "getting a phone". If you already have a contract and just need a new phone than u can just buy a phone but you will have to pay full price for it unless you have upgrades. If you're a new client than yes you would either have to sign a contract or you could just get a pre-paid 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
No, only if you buy the phone at their discount price.
A prepaid phone is a phone you pay for ahead of time and for every minute or text sent usually in a package format such as 200 minutes or 200 texts. A contract phone is a phone you pay the same for no matter what every month depending on the type of contract signed.
Not sure what you mean by 'upgrade' - if you mean change your phone to a new one - then no. Pre-paid phones are usually yours for life. Contract phones on the other hand - can usually be upgraded towards the end of your contract period. Or are you talking about upgrading from a pre-paid service to contract - keeping the same phone - which is possible after a credit-check.
A data plan is where you have a plan for more data on a device I think.
You going to sign a contract or no contract? For a contract to get your phone cheaper you will have to do a credit check.
YES; as long as the SIM works in that phone.
If I had an contract plan with alltel and i cancelled the contract can i use the phone as a prepaid phone
Most phone companies will charge you if you want to unlock your phone before your contract with them runs out. It has been part of the contract
get a different phone
