I was with them for over 15 years, and year after year they would make excuses for why service was bad or slow. They would also make promises that (most of the time) never came to fruition. I found their customer service to be just as poor as their signal strength and coverage, not to mention their business plan.
Sprint is going under. I don't recommend using their service.
I really don't understand why people ask this question. Here's the explanation.
No one here can answer your question because no one knows where you live and the places you commonly go to.
All cellular companies have gaps and weak spots in their coverage. Even in a city, there are isolated pockets of poor reception, so just looking at a cellular coverage map on the carrier's website is not particularly useful.
You would basically need to ask your neighbors and people at the places you commonly go to (work, school, etc.).
I've had AT&T and T-Mobile service over the years and there are places where the signal is strong and places where the signal is weak for each carrier. Sometimes things improve if they erect a new tower, add new frequencies, upgrade equipment, etc. Sometimes there are downed/malfunctioning transmitters and previously good service temporarily worsens.
For me, T-Mobile service is okay at work, rather poor at home, but decent enough for most places I go to justify the monthly cost (I pay $32.53). I wish reception at home was better, but I'm connected to strong WiFi and I can always make VoIP calls. If I step outside and walk thirty yards, I get a much better signal but I really don't care.
The only way for you to find out is to try it yourself or talk to people who use their phones in the places that you frequent.
If you invite friends over to your home, ask them about their cellphone reception right there. That would be the most reliable way to get real insight on the actual performance of any given mobile operator's network at that location.
Check out Verizon as they have some good deals. If you need a single line for instance, UL talk+text and 5GB rollover data for $55 could work but don't know your situation. I'd stay clear of Sprint.
As mentioned networks vary in coverage. Try them out. I think they all have about 14 day bail plans if you don't like it.
Sprint and T-Mobile suck. Either stay with At&t or go to Verizon. Those 2 are the only 2 carriers to have. I left att and went to T-Mobile had them for a week worse service I ever had would have rather had trackfone then T-Mobile. I then left them and went to Verizon and haven't looked back since. Verizon is number 1.
I switched my IUP Sprint 7+ to Verizon last November. After having been with Sprint for over 20 years, dealing with hit or miss service, I can't be happier with Verizon service. Now the fact that Sprint iPhone 7's aren't compatible with Verizon is a whole other story
No, I went from Verizon to Sprint and really, really hated it. I said many bad words about the service and paid to get out of it about 7 months in. I just couldn't take it anymore. The penetration stunk. Inside of malls and buildings and even parts of my house created problems (and I live in a metropolitan area).
The big three VZ, att and TMO have their strong and weak areas. It all depends where you live and use your phone- any one of the 3 may be the strongest. Overall they are fairly close in reliability. I'm with Verizon and for now, they are the best network for my needs. Att and TMO also work well in my area too, just not quite as good.
However I would not recommend Sprint to anyone as that network just is weak almost everywhere and I live in a large metro area.
