Up until I read into it a few days ago, I never considered having a 2nd SIM. But now after reading into it, I definitely see myself utilizing it.
I do a lot of international travel, and T-Mobile has the best international perks. Unlimited free text and data in 150+ countries. However, the data is slowwwww, capped at 128Kb. Although it’s fast enough for voice calls over messaging apps like WhatsApp, and Signal.
Lately, while back in the US, T-Mobile reception is going downhill. So I’m thinking of switching to Verizon, which doesn’t have a favorable international plan. You either get paltry data, or pay $10 a day.
What I’m thinking is switch to Verizon, and get a Travel Pass when I travel, then get a 2nd SIM for data only while abroad. That way I can still receive calls on my primary number.
