Can't send SMS

[Fritz]

Ok

so I've unlocked my XDA and use a 3 sim. I can make calls just fine, I can receive text messages just fine but I cannot send texts messages.

Also, I cant access my sim contacts either. I can get around this by copying my contacts to the PC and then to the XDA but I use multiple PC's and am always forgetting not to synchronise contacts on any PC's other than the one with the correct data so I keep losing it.

Anyone got any ideas how I can resolve this.

I have an update for you all.......

I've spoken with 3 and they have assurd me (for what it is worth) that they have not imposed any restrictions on sending SMS (I wondered because I know alot of people take the 3 contract for the cheap calls and then don't use any 3 services but use the O2 roam facility that presumably costs 3 money) so I have to assume I have a set up or technical problem with the XDA.

When I try to use SIM Manager I get an error message saying "Sim is busy. Wait 5 seconds and try again.". Well I wait and wait but it doesn't get any better than that.

SIM Toolkit does nothing when I try to use it, not even the graciousness to give me an error message.

3 said just type in the servcie centre number and away you go (they also said to uncheck the "use unicode when necessary" box) but that doesn't seem to help. Also after I type the service centre number in and try to send an SMS, which fails everytime, I go back to where you enter the service centre number and the field is blank again.

The error message I get when I try to send an SMS is "Your SMS message has not been sent because the SIM is invalid. Contact your customer service center for a new SIM" Well, of course my 3 sim is valid,it works just fine in the e616.

The SMS messages appear in the "Sent" directory even though they haven't been sent (and they really haven't or at least they certainly haven't been received)
