No dual SIM on the T-Mobile (USA)

[ironass]

For reasons known only to T-Mobile (USA), they have chosen, along with Quick Launch, to remove the dual SIM functionality of the Oneplus 6T. This is very useful to people like myself that use the phone for both business and in private life and means only carrying one phone around. See...

T-Mobile OnePlus 6T vs OnePlus 6T – what’s the difference?

Old Android thinking - People in Europe, Asia and even LatAm cross national borders all the time, so they may need more than one SIM. People in the US and Canada have huge countries and can use the same carrier moving from state to state or province to province.

It's almost 2019 - maybe someone will wake up soon. (Hey, at least we have contact lists - 15 years ago you had to dial each number by hand.)

Reasons aren't known. They want you to use their service called digits.

That really doesn't surprise me, carriers in the US can do pretty much what they want.

All my phones have been dual SIM and I wouldn't buy any model without this feature. Most phones here in Brazil, or in India, are dual SIM, from entry level to flagships, and their huge popularity is not exactly because people cross borders. The main reasons are having two numbers for personal/business, one under contract and one prepaid which can change when a good promotion arrives, two carriers to manage local signal problems or cheap limited data plans.

I remember a carrier disabling in the past the dual SIM functionality on their branded models but it had to stop, not sure if for legal or marketing reasons.

Ironically, this is the only reason why I got a 6T (global). To use with Verizon and Tmobile. I had the XS but neither carrier was 'ready' to support esim when ios12.1 came out.

Beats me, both carriers had been using esim on some of their devices and wearables.

So 6T I went. No more two phones.
