I found this posted on the Verizon support forum by a customer, he said to go into the Wireless Settings/Mobile Network menu and uncheck the Data Roaming box and change the Select System from Automatic to Home Only. After you do that, turn the phone off and back on. I did that earlier today and so far it has stayed on 4G and hasn't bounced between 3G and 1X like it has been.
If anyone is having issues keeping 4G, you might want to give that a try.
For the battery cover, I too have seen the metal connectors on those. The ones on the middle side are for the Bluetooth (it says BT) if you look close enough, but the other two connectors on the top corner don't say what they are for. If I take off the battery cover, the phone will change to 1X in the matter of a few seconds.
I tried what you suggested many times yesterday, and the Verizon rep at the store tried it too. I tried it again today, and still a no-go. I am leaving to have it exchanged in a few minutes. Thanks for posting that though, it was worth a try, maybe it will help someone else who's having similar issues.
I have gone through 1 Thunderbolt phone in 3 days. I am now on my second and it has the exact same problem that pete4www has experienced. I took it back to the store after trying every possible option. They worked on it for an hour and suddenly it started working on its own. The first phone allowed you to setup your Gmail account on the phone for about 30 minutes. After that you could no longer do anything with any Gmail account. It kept saying that there are connection problems or the mobile connections are turned off. Worked with Tech Support for 2 hours and they determined the phone was bad.
Thinking about switching back to a BlackBerry or Iphone!
I ran into this issue also but there is a problem with the network that verizon has built. You can force the thunderbolt into a straight 3g mode and that has worked for me. Here is a link to the dissusion on verizon own website
i hope this helps you beacuse it helped me anyway
I had this issue before and what I did since I just got the phone was to do a factory reset and that solved the issue for me. It seems that the initial setup on the phone did not work correctly but after I did a fresh setup, it now seems to work just fine.
I've had the ThunderBolt for a couple of months now and two firmware updates... the Mobile Hotspot has always been unreliable -working steadily for hours at times but more often in fits and starts. As you describe, the WiFi connection between PC to the TB is rock solid but the TB loses connection to the mobile 4G network despite showing 5 bars of signal strength. You can see the Hotspot app (and even the 4G top screen indicator) flash off an on, sometime disappearing and re-appearing. It happens in the same location, when I'm traveling, in different cities. (The one odd exception was when I was on Maui recently, 5 days before the announced go live date for 4G LTE where I was able to stay connected steadily... (perhaps a traffic load issue?)
Anyway, I do not believe it is an individual device issue (my co -workers are seeing the same thing) but probably either an antenna design flaw possibly combined with a firmware bug. I also have a Verizon 4G USB device and that connects rock solid, just sitting next to the TB that's sputtering along so probably not a network issue.
I am extremely disappointed as I am paying for this crappy non-service and to make matters worse, I depend on this for my business and since it's not reliable, have had to buy another USB device and yet another 2 year plan. The final insult is that neither HTC nor Verizon is taking responsibility and basically is taking the stand that "we got you for two years" we only care about getting new customers -the heck with existing customers.
I am having the same issue with my phone. And when I called Tech Support, the guy had me factory reset my phone as well, but the 3G still refuses to work. So that won't always fix the issue.
