Atrix HD - Having intermittent signal loss using Straight Talk.

[applehater87]

The wife and I have Atrix HD phones that we bought used but in great condition a couple months ago. We purchased the Straight Talk micro sim kits from walmart.com and set up our service. We previously had Samsung Captivates also on Straight Talk and they worked flawlessly. I put in my APN settings and I get data and MMS perfectly but occasionally I get a red triangle where my signal bars should be and my phone says "Emergency Calls Only" and I will wait 30 seconds or so and my signal returns.

I live in a fair sized town and have always had 3 or more bars of at&t service with phones in the past so I do not think its an issue with poor coverage. I am attaching pictures of my APN settings.

Any help would be appreciated.

I am having same issue with atrix hd on S.T. moved from att. First month was fine now. I just started getting a weak lte signal at home the same time this started and I think that is the problem. Trying to figure out how to disable it

Having the same problem, but only on wifi. I was using the old non lte sim before with 0 problems. Anybody have a fix or know how to turn off the lte on wifi?

I have an Atrix HD as well as my girl friend. I "upgraded" to the LTE sim and have had the same issue you describe since then. My girl friends phone remains just fine with the old SIM card in. I can't get support to listen to what I'm telling them it seems. It's not on the prompt cards so it doesn't exist basically. They told me it's an isolated incident and that if 10 people have the same issue, then they will follow up with it. I know this is a bunch of crap. I ordered a new SIM card last week in case I got a faulty, early version. They new card looks different but only worked right for a day and now it's the same red triangle/mobile data connection lost. The only time it doesn't seem random is after I hang up from a phone call, almost always cuts out then.
