I've had net10 since I can remember many years, my daughter pays 130 month for At&t service after using so many gbs she is up charged, I pay 45.00 month it's 50 but get 5 discount for having auto Bill each month, for that money I get At&t service too, my daughter says her service is better, um okay, so what At&t sends a signal down and says hey she's a net10 user don't give her as good service, ridiculous right, any way so I get At&t with unlimited talk, text and internet service, never any overages, oh and no long term commitments, no contracts, the bill is always right and the service clear, customer service is always good to me, you can bring your own phone which allows you 8 gigs at lte speeds then goes to 3 g. I have never ever seen any difference in speed, I buy an unlocked phone and a net10 sim card, if you want T-Mobile or Verizon you just have to buy compatable phone and sim, At&t is a GSM phone, there is no reason to keep yourself into these long expensive plans, I think the reason people do is because they get phone they want free ... but these days there's plenty of great options for good priced phones, I use a Motorola these days I paid 200 bucks for it, it has Turbo charge something an iPhone doesn't have, plenty of storage lasts all day battery etc...
Update December 2018

Have switched phones
From Blu to Motorola..BYOP-BRING YOUR OWN PHONE from Net10 very helpful..
