Cannot send SMS in EDGE; WCDMA OK.

[PGMMA]

I can not send SMS when in GPRS/EDGE areas - receive is OK. When in WCDMA (3G) areas, SMS works fine. Has anyone else experienced this and perhaps found a solution?

Hi!

I also have problems with SMS sending. More or less with any network I am in. Usually I can only send one to two SMSes, then I need to reboot to be able to send/receive again. SMS just hangs for a moment in Outbox, then an error message is displayed, network connection drops and then reestablish, SMS is put in Draft. VERY annoying!

Had the SMS sending problem (send 1 or 2, then had to reboot or rest went to drafts) when I first bought my phone e last year.

My problem? Old outdated SIM card. Went to dealer and they gave me a new one. Problem solved!

I did change SIM four times in the past 10 days. From the latest to the oldest my mobile operator has to offer. To no avail. Strange thing is that I have tested some SIM cards I could get my hand on (my father's for example) and two of them did not have this problem.

What could be the issue with SIM card? Why some are "outdated"?

Good question. I'm a pretty techy guy, but I know little about SIM cards.

I asked 5 techs who seem just as clueless. They said:

1. Newer SIM cards have More towers listed (doubtful)

2. Some SIM cards aren't compatible with 3G phones (maybe)

3. SIM contacts are dirty (no)

4. SIM might be overheating (no)

5. Some SIMs draw more current in certain network modes (doubtful)

I bet it IS your SIM. Ask if they have a 3G-compliant SIM. T-Mobile USA has no 3G yet but their SIMs are supposedly compatible. Who knows :(

Thanks for all the replies! I tried a friends new SIM and it doesn't work either, so I know it's not that. Re-booting doesn't help either. I am on the T-Mobile network and it works as soon as I am in their 3G area. It used to work on GSM until I upgraded to the official GPS update ROM and then it hung a few times and last week stopped sending altogether. It gives me a message that it is unable to send and moves the SMS to the drafts folder. Receive is OK. Is it possible that the radio (1.38) has become corrupted and maybe a new version (1.41) will solve this?

Re-booting only helps in sending one to two SMSes after reboot (and receiving queued ones). Otherwise I have just the same behaviour as you describe. I have also noticed that until I tap on OK on SMS error message, I am not available for incoming calls either! Do you also notice that after SMS error message network drops and reconnects? I have tried some friend's/family SIMs and majority did not work, two of them did. I don't know why. Where will 1.41 version of radio be available? Is it official?

I haven't tried this yet, so I don't know if it will help.

I definately notice this problem as well. Always when the message is 2 SMS long... never can send. Perhaps it is the same problem as when the call is ended as soon as it is dialed, I read on one thread that the phone has trouble when switching to a 3g tower or not... I have a brand new ATT sim (cingular customer) in the Wash. DC area and I still have problems sending large SMS... sometimes reboot fixes but most times not... been searching also... I'm going to try to choose GSM only and vice versa to see if that makes any difference... the only other option for SMS is "Use unicode when necessary" does anyone know if that would fix?

I have now received fifth replacement SIM (looks like a very old and used one) from my mobile operator here in Slovenia, Europe. SMS sending and receiving now works like a charm! Strange that some SIMs work for no obvoius reason.

The phone has no problem switching between GSM and 3G (WCDMA) and in fact SMS works perfectly in 3G covered areas. I cannot send even a one word test, let alone a large message in my GSM area. I recently noticed that I can send SMS in some areas and not in others. Of course, I live in an area where I cannot send. What's weird is that it used to work. It may be that T-Mobile updated the network in some areas and that this is not compatible with Windows Mobile phones. My Sony Ericsson and Nokia phones still work. I'm hoping that when WM6 (official or at least Dopod) comes out, SMS will work properly again.
