I just got a new phone from o2 but its a 3g phone so they sent me a new sim card. Now my question is that i wasnt planning to keep this phone but o2 told me to phone up and transfer my number from my old o2 simcard to the 3g one. Should i still do this or is it ok to just leave it as it is?
Only reason im asking is that the 3g simcard im guessing has a different number on it so would this not be the main number on my account unless i have it switched with me old one. And if i did switch the numbers would it be ok to use the 3g simcard in a non 3g phone?
Sorry if i didnt explain that right, i would phone up o2 but im at work at the moment.
