MDA Pro German unlocked; UMTS still only works with T-Mobile

[stupiddog]

Hello,

thanks to buzzdev's great tool (you are the greatest!) my MDA Pro German now accepts all SIM cards. However, with every SIM card I tried (Eplus/BASE, o2 with UMTS enabled) I never get access to UMTS, even in the center of my town. With the T-Mobile SIM however, UMTS works immediately. Has anybody else experienced this problem? I also tried to hard reset and skip the customization.

Maybe you should check if the other providers:

- supports UMTS
- your connection settings are right
- you need a special account to use UMTS
- UMTS is available in your area with that provider

If T-Mobile enabes UMTS for you doesn't mean all providers do.

Yes, I ordered the UMTS option which caused all my SIM-Cards to be replaced by USIMs. The town I live in is medium-sized (300,000 inhabitants), and I checked about eight places - no success. (Typically, UMTS is available in every German town which has about 50,000 inhabitants or more)

What happenes is quite weird: When I switch the phone on, enter my PIN and connect to the network, the UMTS Symbol ("U") appears for about one or two seconds. Then it disappears, the connection gets lost, and the phone reconnects by GSM. It seems that the phone (or the provider?) throws me out just after a successfull UMTS connect.

I also verified that the GPRS/3G connection is set up correctly (APN surfo2, no username and password).

you probably already have checked the radio band settings, but its worth a try. have you enabled umts band in telefon - einstellungen?

Yes, UMTS is not disabled; I also tried "WCDMA only", but then no connection can be established.

hmmm, have you tried a hardreset and/or a new/different rom?

Yes, I thought that maybe there was some stupid locking in the T-Mobile GER ROM, so I used the latest Qtek German ROM, I also tried the O2 XDA Exec Launch ROM (UK), but nothing changed.

Are you sure there should be no username/password ? http://www.taniwha.org.uk/gprs.html suggests that it should be guest/guest.

Yes, the website you mentioned is a bit outdated. The official o2 Website (Germany) http://www.o2online.de/o2/kunden/technikundeinst/umts/tools/manuell/index.html states that username/password are "nicht notwendig" (=not necessary).

Ah well, I thought it was worth a mention.

Good luck

i guess the question for another radio rom is obsolete.
