With my experience there tends to be some some "Dead Zones", have you checked the coverage map? it could very well be that your home is located in a bad signal area.

 

I have the same issue sometimes. But in places where my coverage usually works I Live in Davie, FL and at my house I have full signal and my data drops out sometimes. One thing you can try it works for me 100% of the time, try toggling your wifi on and then back off a few seconds later this seems to reset the data connection or something but always makes it start working again.

 

Same with airplane mode... this generally works across the board for android devices that hang on a data connection.

 

I have been having the same problem so I called Metro yesterday and they told me that they are having a problem with there network right now

 

mine has consistently been having problems to which a reboot always seems to fix

right now i can't send MMS, its actually telling me the service is unavailable. metro's problem or my problem?

 

I don't know, because my data problem has come back on my replacement phone now. Green arrow sending, and I have to wait forever to actually do anything data related. I can't do anything until it stop sending, and it seems to be getting worse.

Bad enough that I'm thinking about switching carrier's ..with metro jacking up the prices on their plans .. 70 bucks now for unlimited and now all these data issues.. the reasons that made me pick metro over the rest are becoming non-factors.

3g on other carriers are faster than our 4g, with comparable price plans and reliable data. Plus cooler phones ..
