I switched my family plan over from At&t about six months back and have had really terrible reception issues ever since. We live in a somewhat rural area (Wildwood, MO), so it was kind of to be expected, and T-mobile was quick to send me a cell spot for the house. The cell spot has certainly helped, but it's frustrating when I can't get a call or text out while at the grocery store, my son can't call out while at school, etc. Additionally, it's common for us to be on calls coming and going from the house, and 90% of the time it drops when converting to/from the cell spot. Our municipality is huge and mostly rural, but we're in a heavily populated and well developed portion of it. When we first switched we had two GS7s and a J3. I have since upgraded to a GS9+.
All of our grumbling aside, we've been dealing with it. I recently changed jobs and now work off of a major highway in Maryland Heights, MO; literally the building is right next to the highway. To boot, I'm on one of the upper floors and no more than 30 feet from the window. At any given moment I can look at my phone and always have 2-4 bars of 4G showing, however, when I attempt to use anything requiring data I almost always get failure. Most of the time I'll get a ton of notifications all at one time as the phone connects for a brief moment. If I try to check any of those notifications that need to call back to get data, failure. I have also had difficulty making/receiving phone calls and texts, despite showing service, forcing me to walk to the window or leave the building to "get out".
My frustration is getting to the point that I'm ready to go back to At&t as several new co-workers say they have great service throughout our building. I guess I'm partially here to vent (though I've heard/read that T-Mobile has terrible building penetration issues), but also to ask is there anything I can possibly do to help? I can't/don't want to rely on wifi. I've heard that 600Mhz spectrum roll-out is happening elsewhere. Is there any timeline or ETA for the St. Louis area?
