Hello,
I'm not sure if I am posting in the right place, feel free to move this if necessary!
I recently bought a phone in Singapore. It is based on a HTC Butterfly / Droid DNA, but it has 3 sim cards.
Everything works fine, except that back in Europe I can't get a data connection via the sim cards. WiFi is not a problem.
I know the problem is not the sim cards, as everything works fine when I use them in another phone.
I have tried all the possible menu options on the phone, but nothing seems to make any difference.
I think that either something is not working properly on the phone (hardware or software) or it might have to do with the radio frequencies that are used for internet access. But every information I have found about this says it shouldn't be an issue.
I used the *#*#4636#*#* code and in the menu that pops up it is possible to change the radio frequency. There are several options but again, nothing really seems to make any difference.
Unfortunately I didn't test the internet access while in Singapore, which would probably help answer some questions now.
Any ideas or suggestions?
Thanks!
