Can't send SMS

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)
ROM Version is 3.17.03 Eng (in fact it's the XDA developer ROM)
ROM Date 05/15/03
Radio Version 4.16.00 (I down graded to this to get the thing unlocked)
Protocol Version 32S54

[Q] SMS Messaging Problem

Hi,
I recently upgraded to an HTC HD2 that I bought on eBay. It was an O2 phone that had been unlocked so I could use it on Orange. When I picked it up, SMS messaging was working fine, unfortunately, a dodgy app meant I had to do a hard reset and since then I can't send or receive text messages.
I've checked that the message centre number is correct. I found it in 2 different places but it's the same in both (which is the number that Orange provided).
Any help would be much appreciated.
Thanks,

Unlocked optimus t

Quick question. I tried to search but couldn't find anything readily available.
Bought my wife an unlocked optimus t. She will use it on at&t for now (another few Weeks until contract of up) them switch to T-Mobile mobile no contract. Right now I switched everything to at&t and have data working (edge of course). The problem is that she can receive texts, but it won't send them. When she his send it just says "sending" but they never go through.
when I go into SMS/mms settings I do see one setting which says "messaging center" and lists a phone number in it. The number it's not my wifes number. I write down the original # and put my wifes # in that. did not work. I don't know if that had something to do with it, but I an guessing that must be routing texts through some t-mo center and not at&t.
Any help? Thanks in advance.

[Q] GALAXY S2 I9100 cannot send sms

Hi,
Since yesterday i cannot send any sms/mms.
The mobile is able to receive sms but when truing to send a new message i get a sending..... status and that's all. The message is not send.
I have checked the Message center number it is Ok
When changing my SIM to another phone ......it works
I contacted VODAFONE to send the setup.....they did it but nothing
I DO NOT WANT TO FACTORY RESET THE PHONE.
Does anybody knows something?
Service stopped or anything?
PLEASE HELP.

HELP NEEDED!!! Cant send or recive calls!? PLEASE HELP!!!...

EDIT: Just tried a 3 sim card and it worked so I will get another T-Mobile Sim to see if the problem is a didgy sim card...strage as the sim works when I put it in a micro sim to sim adapter in another phone!?
Im in the UK, with T-Mobile and randomly cant send/recieve calls or texts
I called T-Mobile and they refreshed the network settings but I still cant call...they said it wasnt anything to do with network coverage as it was displaying i had signal, but in call settings > additional settings or call forwarding > voice call:
it says "Network or Sim error"
my sim works in another phone too so its not a dodgy sim...so it is 100% down to the phone that I cannot call or recieve calls or texts so not just call settings being messed up, problem surfaced 2 hours after flashing Foxhound 0.3 (but in those 2 hour calls/texts were working)
I have done hard reset, and facory reset, restored a backup...also flashed stock XXLF2, and also LF8 but all with no luck
My IMEI number is displayed in about phone, it is displaying full signal, and T-Mobile in the dropdown menu and im able to use my mobile data from T-Mobile so what is wrong, and how can I fix this?
Would be forever grateful to whoever can help me out...even if your not sure any ideas are welcome as my £500 phone is as good as bricked to me!
I will take it into T-Mobile to see if they will replace the handset under warranty but how do I go about making it seem it hasnt been rooted or flashed custom ROM, I know I need Triangle away but what order etc?
Thanks allot
