Yes you can.
Yes
Provided the handset is not locked to a network then yes.
"An orange sim means nothing, but an Orange SIM card is a pay as you go type of card. Orange is a mobile phone service company, and according to their website, a sim card is free."
Contact your service provider and they should be able to transfer your Pay and go contract to your sim and cancel your Contract account.
Yes it does. The IMEI and SIM are totally different. The IMEI number is hardcoded into the handset and cannot be changed for a specific handset. But the SIM can be changed.
It depends on the handset. With a SIM only contract, you're expected to use their SIM in an existing phone (rather than them supplying a brand-new one). Therefore, if (a) your handset is already 'locked' to the 3 network, or has been unlocked from its old network, then it should work perfectly well.
All sims are pay as you go unless purchased with a contract, the only way a sim won't work is if it's blocked.
at any time by 1: purchasing a new one and just simply putting your sim card in to it as the contract is carried on the sim along with the mobile number. make sure it is compatible with your network. 2: if out of contract contact your service provider ie: t-mobile, orange etc and request a new one for free, clearly stating you are happy with your current contract but merely want a new handset. they will tie you in again for minimum term ie: 12 or 18 months. aldepending on the device you request will aldepend on if free or you have to pay a small cost.
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.
One can find a free Pay As You Go Sim card for the mobile network Orange from the official Orange website or from an official Orange brick and mortar store.
Assuming you're asking what they are, how they work etc. Nothing is free... When you first buy a mobile - you pay a higher monthly charge to cover the cost of the handset. If you're at the end of your initial contract period, and happy to keep the phone you've already got, you can usually switch to a SIM only deal. This means you carry on with your current provider, but pay less monthly rental. I'm with 3-mobile and had an initial 18-month contract, costing £12.00 a month. At the end of the contract period, I switched to a 12 month SIM only contract, which only costs me £4.00 per month !
Yes - provided the handset is either on the same network as your SIM or the handset has been unlocked form any network thus accept any SIM card.
