Disclosure first: I run a travel eSIM site, so I have an interest in this topic. I’m posting numbers rather than a pitch, including the plans on my own page I’d tell you to skip. Mods — delete this if it isn’t wanted, no hard feelings.
I searched the forum first, as the rules ask. The SIM threads here are mostly 2016–2019 and about physical SIMs and pocket wifi, and Cheapo’s own prepaid SIM guide has “(not eSIMs)” in the title deliberately. So this is the other half of that shelf, priced today (22 August 2026, USD).
The tiers worth buying
