Desperately need help with my XDA and 3 network in the UK

[jollster101]

Can aybody please help. I have my XDA and at present an NEC e606 phone that came as part of my contrat with 3. The XDA is unlocked and I can use my 3 Sim Card with it and can happily make calls, receive calls and receive text messages on my XDA.

I cannot however send text messages using my XDA with the 3 Sim Card. Whenever I do I get an error that says 'The sim card is invalid. Please contact your service provider for a new sim card.' I do not want to have to use the e606 at all and am desperate to try to figure out why I cannot send texts via my XDA. I have put the sim back into the 606 and it sent texts fine so I don't think its the sim.

Also in the 606 the sim is read fine for the contacts stored within but in my XDA when I go to Sim Manager I get an error every time saying 'Sim is busy. Wait 5 seconds and try again.' Does anyone know why I am getting this error??

Apologies for what are probably basic questions but I am new to the XDA and am not too sure which way to go about this or what settings (if any) may need to be changed. It just seems strange that I can receive texts, make calls and receive them as well but cannot send texts.

Anyone have any ideas??? Any help would be MUCH appreciated.

With thanks

Hi

I STRONGLY believe that a 3 sim will never work on a GSM phone.

the 3 network uses 3G and NOT GSM. 3G is some new way of doing things that allows faster video hence all the adverts involving ducks etc...

sorry

If that is the case surely I shouldn't be able to do anything with the sim. It seems bizarre that I can receive texts on my XDA with the sim and can make and receive calls on the XDA with the sim as well. The only thing I cannot do is send texts with it.

Does this seem right????

With thanks

3 is on the 3G spectrum, not 800-1900 GSM.

You are able to use the SIM card though because, 3 have a contract with O2. When out of 3 coverage you are roaming, just like abroad. To maintain service you connect to the o2 GSM network. now as to what level you connect I don't know.

You can receive texts ok. So do you use a message centre number?
You can make voice calls, o2 gsm network.
what about internet, video, data, etc....

Just remember where you are. Simple questions, are never simple!!

I haven't tried the internet, video, data etc as I never had any intention of using these services from 3. I went with 3 because of the amazing deal they are offering on X-Network minutes. All I want ot do is be able to do the normal stuff (make / recieve calls and send / recieve texts) as you would on a normal mobile.

I know that 3 have there agreement with O2 and that I drop onto there network when not in a 3 service area for calls. I am not totally sure about the settings for the message centre number but surely these would be on the sim card itself anyway. As I said I can send texts using the e606 handset but just not with my XDA. Why would I be able to receive texts using my XDA but just not send them.
