"Cannot connect for an unknown reason" with every ROM I tried

---

I bought a used Orange UK TG01, unlocked it with an unlock code, then flashed some cooked ROMs. Voice calls work perfectly, but a "Cannot connect for an unknown reason" comes out immediately when I use anything that needs a data connection. This even happens with a stock Hong Kong WM6.5 ROM.

Is my TG01 defective? I flash ROMs with SDDL+ and my microSD card is a Transcend 8GB microSDHC Class 6. The only things I haven't tried yet is using a microSD (<2GB) card and using the pin shorting method to flash ROMs instead of using SDDL+.

I'm in Hong Kong and my mobile operator is PCCW 3G. All connection settings are correct. The same settings and SIM card work with my HTC TyTN II.

Try this....

Change your sim card with your friends or your wife's. I am thinking that your phone company is the problem. I had the exact same problem with my phone here in Japan. Said something just like your message. So I swapped the sim card with the sim card in my wife's phone and boom... my phone worked perfectly. I had to call my phone company over and over and over again, then they said that they will "refresh" my phone account and it took three days. So... just try a different sim in your phone, the problem you are describing is EXACTLY the same as I experienced. No data connection, but SMS(I think.. I am not sure, it happened to me three years ago) and phone works fine.

Check it out, tell me what happened when you swap sim cards?

Luckily my operator happens to be carrying out some network upgrades which requires me to get a new SIM card from them, no phone calls needed.

I got my new 64K SIM card and bam, everything works perfectly now! The chip on the SIM card is smaller than my previous SIM card.
