My phone is Motorola XT1033 dual-SIM (Lollipop 5.1)

* have active mobile-data internet packages
* can connect and open provider's website (to check package status & quota)
* valid APN settings (at least following provider's instruction)

There is a problem on mobile-data connection, see the differences here:

Data ON, Wi-fi OFF

* there is exclamation mark on mobile-data signal bar
* NOT connected to internet (even the signal is H)

Data ON, Wi-fi ON

* there is NO exclamation mark on mobile-data signal bar
* connected to internet

What I've tried so far

* reboot phone
* off-on mobile-data
* re-attach the SIM card
* install my SIM card to another handset (can't connect to internet)
* install another SIM card to mine (can connect to internet)

Does anyone have the same problem? I'm looking forward for the solution, thx

  • Have you tried switching to GSM only mode ? maybe the WCDMA network falling short in your locality. – reachrk Jan 11 '16 at 3:14
