Interesting! Same for me. Did not occur to me to try data only plan since using with dumb/glovebox phone. Thank you! At $20/year all-in using existing PAYG balance (with optional $10 auto top-up) and minor headache every 3 months, not too bad!
U can’t use existing PayGo balance to buy a monthly plan.
My post is poorly worded, sorry. I meant I already have a PAYG balance that I would be using for PAYG voice/text. Fortunately, I have exactly $20 Tello Dollar to cover the first ~12 months (based on current terms, 4x $5/month/plan), then after can pay with Paypal or credit card.
