Advice on an O2 3g sim please...

borosteve_2

Hi, I'm a bit unsure about this so I wasn't sure whether to post this here or in the Mobile forum so in the end I've put it in both. Sorry if this upsets anyone but here goes:

I've just bought a new contract on O2 for my mum. The deal was 200mins 200texts which is more than enough for what she needs. She wants to keep the Sony Ericsson phone I bought her about a year ago as its pretty easy to use and not too technical etc. However when the new simcard turned up from O2 it was 3g. Now the phone she has is NOT 3g so will this cause compatibility problems?

Its just that I remember someone saying that if you use a Three network sim in a 2g phone the network can tell and it may void your contract (but not in a good way).

Any techie advice very welcome .


Thanks in advance for any help.

thats 3 for you though.

the o2 sims are mostly 3g ones now i think but it should work fine as o2 have their own 2g network unlike three who pay to use oranges 2g network when you are not in range of 3's 3g network
