3g sim card

[jimblob]

hi guys does anybody know if it is possible to get my o2 xdmini s to except a 3 sim card, it excepts all other sim cards (virgin - vodafone) etc
thanks, jim:confused:

Think the simple answer is no.

My understanding is that three use a different frequency and specification - ie wideband CDMA for their mobile coverage, which is not compatible with sims from other carriers using gsm and/or 3gsm services.

If you correctly use the word "accept" instead of "except" in your future posts it will be much easier for people to help you.

one thing that i know is that it will work but no 3g

how? i sim unlocked my G4 mini s. It works with o2, vodafone and should be fine with orange.

But I did check to use my 3 simcard. However, it doesn't accept the card at all. (not only can't use 3G, but no phone feature is available to use)

Q: How do I know my G4 has ever been CID unlocked?


Try SIM Unlocking again. A 3G sim means that it's capable of 3G speeds in a 3G device. I'm currently using a 3G sim in a non 3G device and all is good.

If you didn't CID unlock your device yourself....more than likely it's still CID locked. G4's were only able to be CID unlocked by imei.com or something like that till now. There's a new CID unlocking tool floating around that works on G4's. Give it a try.

Thanks for the reply. But i thought the 3 networks and other networks are working completely different.

I have a sim-free phone. I can use O2, Orange, Vodafone, T-mobile, etc. But when I put my 3 sim-card in. It doesn't allow me to use it. I don't care the 3G speeds. It will be fine to me if I can use the 3 sim card to make a phone call.

The same situation for my Wizzard (O2 Mini S).

i sometimes use a 3g sim and its the same as my regular sim but as long as the sim is for a GSM network it will work but of curse it has to be on a sim unlocked phone

My Wizzard is Sim Unlocked, CID locked. I can use my regular sim cards, like O2, Vodafone, etc.

But why can't I use my 3g sim card to make any call? Any idea about this will be appreciated.

i believe the wizard phones arent made for 3g. so thats probably why your
3g sim wont work.

i emailed imei-check.co.uk and this was the reply

"This is TECHNICAL IMPOSSIBLE. Your device is a 2G device and can handle all GSM SIM cards.

"3" (3G network) does not have GSM SIM cards. They use special U-SIM cards (note the U in front) which are NOT GSM compatible.

In short: To use a "3" sim card you need a 3G/UMTS device which can handle U-SIM cards. Your device is NOT a 3G/UMTS device and thats why it will NEVER be able to use a U-SIM."


that sucks ive got 12 months left of my contract:(

Exactly, I have 17 and a half months left for my 3 contract.

But the guy "ultraprimeomega" above mentioned, he could use the 3 simcard as well as other simcards. It's very strange to me
