MAXX HD Locks, Power Cycles, Prompts for Intl Data, Drops network. Suggestions?

[LucidAnne]

I have had horrible issues with this phone since I got it.  It turns off and back on by itself, locks so badly I can't answer the phone, Drops Wifi and 3G connections, unmounts the SD card or just wipes it (says data is corrupt), and is constantly prompting me to turn off data "for this trip" to avoid International data rates.  Last time I checked, the grocery store in Nebraska was still considered U.S. Soil.  Any suggestions on what I can do to resolve these issues, other than throw it out of a moving car and make myself feel better?

Here's what I would try: (in about this order)

1. Reboot the phone.
2. Clear system cache/wipe cache partition
3. Remove the SD card, reboot the phone, and use it sans-SDcard for a while.
4. Get a Class 4 or Class 6 SD card 32GB or less.
5. Remove and reinsert the SIM card to force the network to re-find you.
6. Factory reset (Wipes all your data, be sure and back up everything including texts.)
7. Get a new SIM card.
8. Warranty exchange your phone.
