Interestingly, perhaps, I have just finished transferring my iPhone from Xfinity (dumb**** tech support), to AT&T (for 1 week - not much better) to Verizon (for 3 days - also in the same league) - ... and finally, of course, to the best carrier for tech support = T-Mobile. Using my Senior Discount I get 2 lines for $60/month plus my Apple Watch Ultra 2 for another $10/month for $70/month. Which makes it expensive compared to the others, except now I have a second line for business.
So, yes, I pay more for T-Mobile. But it is owned by the Germans, I even get tech support with a slight German accent. And they don't miss a beat, they are relatively very procedural, and I understand them to the point I am comfortable with them. - So much better than a usually garbled Spanish/Hindu accent out of India, the Phillipines or Mexico or someplace else. (Of course they are
supposed to speak English in India and the Phillipines.)
When you deal with a carrier, you are
not dealing with one person, but rather a large team and large organization. Always think like that. Judge the team and organzation you are working with as a whole. Are you always getting a strong chain of links or a chain of sometimes weak links. Those weak links, even if they are few and far between, can take up a lot of your time.
If you feel a need to switch carriers because of poor service, don't make the mistake of switching to another carrier that isn't known to have better tech support - because that can turn into a fxxcked up mess.
As for my AT&T Fiber Optic, at 2.5G, - so far that is absolutely Great. Especially running it on 2.5G-10G routers and switches.
NOTE:
"Key Details:
- Ownership: T-Mobile US is majority-owned (approximately 53% as of the latest available data) by Deutsche Telekom AG, a German telecommunications company based in Bonn, Germany. Deutsche Telekom acquired control through a series of mergers, including the 2013 acquisition of MetroPCS and the 2020 merger with Sprint Corporation.
- Operations: While Deutsche Telekom exerts significant strategic influence as the parent entity, T-Mobile US functions as an independent subsidiary with its own executive leadership, branding, and primary market focus on the United States.
- Distinction: The "T-Mobile" brand originated with Deutsche Telekom in Germany (where it operates as T-Mobile Deutschland), but the U.S. entity is a separate corporate structure incorporated under U.S. law.
In summary, T-Mobile US is an American company with substantial German parent ownership, not a German company itself." (Grok)
BTW, the "T" in "T-Mobile" stands for "Telekom."
