I have 3G sim card on the 3 Network and when I put it into my old K750i it says please insert sim, but the phone is unlocked. Any one know why this is please?

maybe the sim is just loose try to remove it and put it back again. most of the sometimes that fixes the problem.

It's because it's a 3G sim card, it will not work in a 2G phone, simple as that.

Since your phone is not a umts phone it does not support 3g networks. Thats why you get the message insert sim This message was posted from a WAP device

That's correct but that is the operator 3 who dont wanna have their cards in 2g phones.
