I purchased a Thunderbolt at the end of August and all was fine until Sept 28th when I started losing 4G, 3G, 1G data connection. I was told by Verizon rep on this forum to do a complete reset, which I did yesterday. Data connection was still spotty the entire afternoon yesterday, so I stopped at the Verizon store on my way home. They put in a new SIM card and said that would take care of all of my problems. Well, of course, I'm still losing connections today. Have only had some 3G, when I know Tampa is a 4G city (and they made a point of telling me that yesterday at the store). Should I be asking for a replacement phone? Also, when I have a VM message, It's not showing a notification that there's a VM. I'm starting to regret the decision that I bought this phone.
rest assured that it is not just the HTC phones that having this issue. I have a Charge and my issues started on 9/28 as well and still have not been resolved. It is not your phone, it is not you, it is Verizon. Read the link below and it explains your situation i am sure. It did for me.
I called Verizon last Friday and they shipped out a replacement phone to me that I received yesterday. I was not happy to see that they sent me a reconditioned phone because I have only had the "new" phone since August 17th. So far, so good, it's kept a 4G connection at the office, while driving and at home, I usually connect wirelessly at home so that has never been a problem. I haven't had any calls yet to see if the VM issue is resolved. I'll post back in a few weeks to see if this is still a problem for everyone. I hate paying for a data connection that I'm not able to use!!
I've had this issue for months. I've done everything Verizon suggested, including new sims, factory reset, toggling Airplane mode, LTE on/off, radio on/off, reboots, *#*#4636etc., and more. Nothing helps. My phone still intermittently loses the 4g connection. They haven't suggested trying a new (not new; reconditioned), but I don't want to go that route; I know others who have gotten a replacement, and it hasn't helped.
It isn't fixed in the upcoming update according to developers forums.
Some think it's due to Verizon's network; others believe it's an inherent problem in the 4g chipsets in these first generation LTE phones. I don't believe Verizon knows what's going on; they're just hoping the issue's fixed in the next gen phones, and the problem will go away. Of course the problem with that is that some of their customers who are stuck with these phones will also go away at the end of our contracts, especially if another wireless company manages to come out with a RELIABLE high-speed 4g network.
So far, it's still working with the replacement phone. Haven't seen anything except the 4G connection. When I stopped in at the Verizon kiosk at the mall a week or so after I started having problems, I was told that it would be an ongoing problem until 1/1/2012 because they were constantly turning the 4G network off for testing so that it can be released nationwide at that date. the guys at the store told me that was a bunch of crap and that replacing the SIM card would take care of the problem. Obviously it didn't but I've got my fingers crossed that this Thunderbolt will work. If not, I'll be back to their customer service department to get replacement phone after replacement phone...I'll keep on doing it until the contract expires in 2 years if I have to.
Sao, I'm glad to hear the replacement device is working well for you. There is a new software that will be coming soon that does improve data connectivity and resolves the voicemail notification issue. The software will be pushed to your device. You can view the benefits of the software update on our support site.
I'm having the same issue now with the replacement thunderbolt. I was getting 4G connection when I arrived in Cincinnati on Thanskgiving day, but for the last 3 days it's gone between 3G, 1G and no data connection. I'll see what happens when I return to Tampa tomorrow. If I'm still not getting a 4G connection, I will contact Verizon again to get a new phone. I will request a new phone instead of the refurbished one I received as a replacement for the original phone that I purchased in August that stopped working. At this point, I'm not very happy with this phone. Unless Verizon will give me a free phone that is better, I'm going to be stuck with this for the next 2 years.
