Currently I found a glitch to get near-free infinite mobile data usable in my country via 3 different mobile carriers giving me far superior coverage as well.
I got a Czech T-Mobile SIM card with the purpose of receiving SMS verification codes. Unlike cards in my country, Czech ones don’t need ID card registration. The cheapest one was an IoT SIM card, so that’s what I took. I found I could get signal basically everywhere with it, since they have multiple roaming partners (Slovak Telekom, O2 and Orange).
For shits and giggles, I’ve used that 200MB it came with since it’s available in EU as well. And that’s when I discovered the 64/32 kbps limit after using up the data isn’t getting applied outside of Czech Republic. It just still goes at full speed.
Charged at 0.00CZK:
The difference with IoT and regular SIMs is that low speed. IoT SIM cards get that reduced speed while regular ones have a hard cut-off with more data amount. Attempt with regular SIM after using up the data:
So really, I can just fully use 80MB for 39CZK (1.59USD) and keep going:
But there is a caveat: Permanent roaming charges. If for the past 4 months the SIM is used more than 50% abroad, T-Mobile can start charging these charges. This year it’s €1.30/GB without VAT. But I can probably just keep getting new SIM cards each few months.
But I am being nice and still mostly using my regular carrier with 300GB of data. I rather keep this as backup. The wholesale market data cap is that €1.30/GB in 2025, so the carrier could get charged up to €390 for that same amount by their roaming partner. Regardless, I am not giving them equivalent of €1.55 for just 80MB either.
