Tmobile is technically different companies in Europe and US, although Tmobile in Europe owns 43% of Tmobile US, and interestingly, the German government owns 32% of Tmobile Europe.
Tmobile is also widely considered to be the worst of the 3 US mobile networks (Verizon is considered to have the best coverage, then ATT, then Tmobile). Their pricing reflects that too, as Verizon is the most expensive, then ATT, then Tmobile.
For that price (approx USD 120) I get 4 lines, so my whole family. I'm not happy about the data breach, but I'm very happy with TMobile otherwise, and I seem to have a better deal than my friends on AT&T and others here in the USA.
