I’m not impartial. I have financial relationships with many wireless operators, including Mint Mobile. I may receive a commission from Mint Mobile if you purchase service after clicking a link from my site. More details can be found here.
Mint Mobile is a mobile virtual network operator (MVNO). MVNOs don’t operate their own networks. Instead, they resell access to other companies’ network infrastructure. Mint Mobile runs over T-Mobile’s network. In most situations, Mint Mobile subscribers should experience speeds that are essentially the same as those experienced by T-Mobile subscribers.
How fast is T-Mobile’s network? It depends. Where T-Mobile offers a strong signal and an uncongested network, speeds will generally be quite good. For the most part, T-Mobile tends to have a strong network in well-populated areas. However, this is not always the case. For details about how to evaluate wireless networks in a given region, see How To Evaluate Wireless Service Quality.
When T-Mobile’s network is congested, Mint Mobile subscribers will generally receive lower priority than T-Mobile’s direct subscribers. Lower priority will, in turn, lead to lower speeds.
In most areas, congestion is relatively rare, but your mileage may vary. In other articles, I explain prioritization in more detail and discuss prioritization policies for services than run over T-Mobile’s network.
