I know this is a "charged" question, but I need a dual SIM, 5G Europe and USA

[irobbie]

I know this will make someone (or most) of you laugh/jump.
I am in need of a Dual SIM, 5G phone that works in USA (ATT) and Europe (Vodafone).
I know that some Bands are unavailable.
I did a TON of research and my brain has melted.
I am lost in all the Bands and Frequencies.....

Suggestions are welcome!

Thank you,

Can check out Samsung or One plus phones

Thank you,
I bought a Oneplus 8T as it is the only one with dual SIM, but even though it says 5G I do not have it!
So probably a Samsung would be better.
It is harder to find dual sims in USA....

US is hard , pixel have sorta dual sim with 2nd being E-sim
What carrier you on with 8T ? Because 5g is hit or miss depending on your area

All new Oneplus 9 series sold in USA have only 1 SIM!
I have ATT in USA and Vodafone in Europe.
ATT is also even more difficult with 5G (I gathered), so I was thinking about changing carrier.
T-Mobile would be probably the best choice for me as it is in Europe as well.

But I am totally confused now......

You're probably going to find it easier to buy two phones, one for AT&T and the other for Vodafone. It's not just the SIM card issue you need to account for, it's the cellular radio chip that every phone has inside. Keep in mind that any SIM just retains your account info with your chosen carrier. A SIM does not determine what bands/frequencies the phone is capable of. So there's a SIM card issue and a phone hardware issue involved -- the SIM just authenticates you to use a carrier's cellular network, but it's the cellular radio that does the actual connection to any cellular network. And unfortunately our phones are rarely modular with replaceable parts, so the almost all phones have their cellular radio chips soldered directly onto the phone's logic board. They're not interchangeable or swappable like a SIM card. That's why a typical smartphone is going to be usable as a universally compatible phone, different carriers rely upon different cellular networks. The issue you're going to have to deal with is 5G implementation in the U.S. is a lot more fractured and spotty than in Europe. You 'might' be able to find a dual-SIM phone that will work with 4G/LTE but AT&T's 5G bands don't appear to match up with Vodafone.

Go here and in the top section there's a drop-down menu to toggle between different regions, in your case you'll want 'USA' and then 'Europe'
https://www.kimovil.com/en/frequency-checker
AT&T 5G -- n5 (850), n260 mmWave (39GHz), n261 mmWave (28GHz)
Vodafone 5G -- n1 (2100), n78 (3500)

Also keep in mind 5G in the U.S. is very, very regional so depending on just where you'll be located it might be pretty solid and reliable, or just as likely not available or dependent on local conditions. If you opt to rely on the coverage maps on AT&T's site do so with a healthy dose of skepticism.

Thank you.
I came to that conclusion as well.
I need to buy a phone in Europe and one in the USA.
I really do not understand it. In this world where we claim globalization (not going into the political aspect of it) the communication system should be the first one to be truly global.
Particularly the US: everything is locked and well controlled by the carriers.
Free market?
