Semi-incompatible sim with new ROMs (can't send texts)...

[fraktal]

For background, my device is a c500 (typhoon) and I've tried various roms (but I'm using the 6.1 one atm). I didn't have this problem with the stock ROM.

I find that, although the phone works and I can recieve text messages, I can't send them because the "text message service center" field is empty and if I enter anything in the box, it clears as soon as I leave the screen.

Also, trying to use the SIM manager (for contacts etc) returns the message "invalid or missing sim".

To me, this seems to be a semi-incompatible sim card. I've seen other phones with the same issue (eg here (http://www.modaco.com/content/htc-hermes-hermes-modaco-com/262819/cant-send-smss-since-updating-the-rom/#entry863097)) so I don't think it's a specific phone/ROM issue. I've tried SDKCerts.cab and using a cab to install the network settings (http://forum.xda-developers.com/showthread.php?t=316763), neither worked.

Has anyone seen/fixed this before? Thanks.

Hmm. I tried an O2 sim - works fine. Maybe it's because my sim is 3G (and the phone isn't)?

Here (http://www.modaco.com/content/htc-typhoon-variants-typhoon-modaco-com/253623/spv-c500-and-orange-simcard-problem/#entry903361)'s a similar thread on modaco that comes to the same conclusion. If anyone else has the same problem, this is probably the solution.
