Can SMS Message Centre numbers be manually added

[jollster101]

I have got my SMS message centre number from my network provider and now want to be able to enter the info into my XDA. I cannot do it automatically by 'Get Voicemail & SMS settings' in Phone as it keeps returning an error.

What I want to know is, is there any way or any software that will allow me to be able to manually enter my networks SMS message centre number into my unit.

Any help would be MUCH appreciated.

Can you be more specific with the type of error message you receive?

Go to Start->Inbox. Take Tools->Options and touch and hold on SMS. Lo and behold, the Message Centre(er) number.

[jollster101]

The error message I am getting is 'Network Error - Unable to read setting from the network'.

In response to your post "Auldg" I did that and entered in the Message Centre Number for 3 (my network provider) and pressed OK. My understanding is that this would have saved the number. Trying to send a text didn't work and I still got the error message "The sim card is invalid. Please contact your service provider for a new sim".

I know there is nothing worng with the sim as it works fine the phone supplied by 3. I have tried 02's message centre number following a conversation with them and this resulted in a failed SMS send as well. I know it is not the XDA as this sends txts using an old T-mobile sim.

When I looked at the SMS centre number again after entering two different numbers neither of them were there. Trying to select a network doesnt give 3 as an available network.

Does the XDA store the SMS centre number in the SIM card or the phone. If its the phone is there a way to hard code my sms centre number into it?? This is driving me mad as I can do everything else with my 3 sim as normal just not send texts

This '3' network, what is it? Is it a GSM provider or a 3G Networks Provider?

[auldg]

Are you in the UK on 3? This is a new GSM/UTMS network and I wonder if the SIM card has new fancy stuff on it the the XDA doesn't know how to handle. You are clearly a VERY early adopter, bless you.

I didn't have to enter my MC number (or Voice Mail number) when using my XDA on Orange so these must be picked up from the SIM. Maybe the 3 sim holds these details in a different place from the rest of the networks?

One for the xda-developers firmware gurus to take a look at I think.

And so can one of the XDA-Developer firmware gurus shed any light on this matter???

I didn't really switch for the new technology that 3 offers, quite the opposite in fact as I din't really need to use it. The reason being was the deal on free mins they offered, but that's by the by. I can still use the 3 sim in my XDA and make / receive calls using the 02 network (this is what it uses if it cannot pick up the 3 network) and also receive texts. Just not send them.

Can any development guru's PLEASE shed any light as to this situation and may be even be able to offer a solution. If its even only that its something that can be addressed in an upcoming firmware ROM.

Some divine inspiration from the gods would be hugely appreciated.

So, let me make sure I am getting this right. You currently have no way to set your SMS service center number in the device, and if you do using the normal options the number does not stick?

OK that said you can do a registry hack telling the reg to override the SIM and use "# you choose" number. See my thread towards the bottom on how to novice level write a reg key http://www.xda-developers.com/forum/viewtopic.php?t=1660

I haven't yet looked up where the reg key for SMS service center number is but I’m going to guess it is located right above or below the location specified in the thread.

I'm just going to guess but I don't think forcing your machine to use a SMS service center number from the device end rather than the SIM end is going to solve your can receive but not send problem. Given the service center, number is what is used to send your SMS. If your device is not reading it from the SIM and you are hand putting it in and it's not sticking this sounds like SIM network problem not device problem, could be wrong though:? Let me know overriding the SIM works. Can you use that service center number to send SMS on other Mobile Terminals (handsets/cell phone) Does a regular cell phone see the SMS service center number from the SIM? If the software set the XDA uses to talk to the GSM network is failing, but works talking to other GSM networks...sounds like a service provider protocol or provisioning problem (the way they have their GSM network set up i.e. do they have their own towers or are they ridding on someone else’s footprint but have or do not have their own switches etc.)

You might also try un-checking or checking the use Unicode option under accounts SMS in Inbox, but this should really make no difference as this is only when necessary protocol anyways, but who knows. I still think it's on your service provider’s end/SIM. The XDA just talks to the network using GSM "Standard" agreed upon protocols for GSM. Now the provider can do whatever they like. These are just suggested standards so problems (maybe) like this from occurring. Anyway, let me know if this makes any difference. Always learning :lol:

Cheers,

You have hit the nail on the head exactly. When I try to enter the number manually it does indeed not stick. I have tried the sim in the original phone that it came with and it works as per normal. All the functionality is there.

The network I am on in the UK is a new network that is giving the 3G technology but this is only being rolled out and is not nationwide. They do piggyback onto another providers network (namely 02) when you are not in a 3G area so that you are always able to make voice calls / send tetxs.

I have no idea as to whether they have there own switches etc as its like trying to get blood out of a stone when talking to there customer services.

I have looked at the thread about editing / creating registry keys and did look at the key that you mentioned. Above the vmail key is an SMS key but opening it led onto all sorts of other fields and protocols which threw me. I am not sure which of these (if any) would be the correct one to start entering SMS Message Centre numbers into or what I would need to hard code it as a new registry key.

To this end I cannot see if hard coding it to make it stick works or not. Can you shed any light as to this??? Would be much appreciated if you could.

With thanks

I'm going to see if I can get my XDA to overide the SIM SMSC, I'll post success or :oops:

many thanks for your help
