I started having similar problems and it required either a restart of the phone, switch 4G to 3G back to 4G again and got frustrated. I suspected it could have been related to a setting I tweaked in Llama or Smart Actions. I trouble shooted it to Smart Actions so I deleted all my events and created one for Charging that specified Cellular Data enabled. This fixed it. I've since gone back into my Smart Actions and ensured that this setting was being forced.
I'm a newb to the droid 4. I had my orig droid rooted with Sourcery. Nice OS. My problem is that I can't get any internet connectivity using mobile network (Verizon). I got this droid on Saturday (4 days ago), and it was in a city that had 4LTE access. I live in an area that is 3G at best. It worked fine until yesterday, and I noticed at work that I had not access. I only have access using mobile network at work, can't use internet at work (idiots, I know). I tried everything I have read so far. It includes this link from above: Droid4 Not sending or receiving data (or intermittant) when connected to Wi-Fi (3G) I saw another post that suggested that I power down and remove my SIM. That didn't work either. A few posts said to use some 3G monitoring tool, but I am getting NO 3G connectivity, so ZERO is all that it showed. ;) I need 3G at least. I was aware when I bought the phone that I wouldn't have 4G, but no one said I wouldn't have ANY internet. I'm thinking of heading into the 'home zone' after work and dialing #288 (or whatever it is) and reload from here. Maybe that will help. I'll let y'all know what happens.
I'm not real happy with big V at this moment. :mad:
Almost forgot, I made sure that I had my Enable Auto IP was turned off. It was.
K - went to home zone, and I got 3G right away. I still did the *228. It went really fast, so I'm not sure what it did. I came back home, lost 3G right at border (where it normally switches to extended network). Went back to home zone, pulled SIM card, *22880, and *22890, 3G still. Back in home zone (extended network) - NO 3G (no network at all when I state no 3G in this post. NO mobile internet). I'll head over to our local collection of cell phone idiots and see what lies they can tell me tomorrow.
All you experts can help me at any time.
I don't know what's causing your issue. However, I can tell you that dialing *228 on an LTE phone is pointless. The network automatically pushes the information (and any updates) to the device while an active SIM is installed.
I'm never sure, and I KNOW that Verizon doesn't really know either. I try to do anything and everything I can to hone in on the real issue. I'll bet you DINNER that they try to factory reset my phone when I go over there. Further, it won't work. We'll see. I'm doing a backup of it all before I go over there.
We have not yet begun to fight!
So, local office oblivious. Call tech support. One hour of doing less than i had already done, and i get a trouble ticket. That was Thursday. Support person is going to call me back on monday. They think it is a localized issue. Weeeeee this rollercoaster is fun!
OK. So Saturday, technical dude sees that I am on the network (which I am, in a 4LTE area 60 miles away from my issue), and leaves a message that it must be fixed. Let me know if I have any other issues. I call Monday, and the tech is pretty good. Acknowledges that the previous tech is a buffoon (basically), and he is sending me a new SIM card as that can be the problem. I don't think so, but I know how this stuff goes. He DID say something interesting, though. If you perform a #228, blah blah too many times (like 2-3), it screws up the SIM card. So, yet another misinformed tech support dude. So...the struggle to get what you paid for continues. Note to self: Call and do NOT pay for mobile network this month. :-)
(oh, and NO call from the nice support person as promise above - figured)
Good news! They sent me a new SIM card. I pulled it in the home zone. I had to get Verizon to update my account with the new sim number (I should have done it first, but not near a computer to do so). It worked!
I drove home, into the extended zone, and I have 3G. Sweet!
Thank you Verizon technical support
