Hi All

This may sound like a really dumb question to a lot of you.
Over the last few years I have had a few mobiles, but they all have been second gen and easy to swap.
If I change my old SonyEricsson K750i for a new 3G set, is it still possible for me to use my old 2G, O2 Pay as you GO sim card in a 3G hand set?
Then is it just as simple as just a sim update???

3G is a higher bandwidth. Meaning you can surf and download content from the net, people, mms etc a whole lot faster than GPRS meaning less time connected and less 'online time' charge.

I dont think you have to change a 2G sim to work in a 3G phone, unless you want to use 'video telephony' then I think the sim will need to be updated and depending on your operator provider, you will be charged for video calls

Hey guys, great site. Just registered and been looking around, thought I might offer something here.

I work at Orange (sigh) and there you can put a 2G sim in any 3G phone but you wont get any of the 3G features. A network update wont fix things. it might be different on O2, but at Orange a 3G sim card would be needed to get the features.

2G phones are capable of this stuff
# GSM 850
# EDGE
# GSM 900
# GSM 1800
# GSM 1900

3G phones are capable of this
# UMTS 2100
# GSM 900
# GSM 1800
# GSM 1900

mainly the UMTS 2100 part.

hope this helps.
