Our verdict on each
4ka
4ka suits Slovak subscribers who want their home plan to roam rather than buying a travel eSIM, and it starts at €5 with coverage across 18 countries. The trade-off is the fair use policy, which caps the EU share of the unlimited data.
Visible
Visible suits US travelers who want a budget carrier plan for home and abroad, with unlimited data, 5G and hotspot sharing. Global Pass extends it to 140 countries and the home plan starts at $25 a month, though roaming data is priced by the day and capped by a daily high-speed allowance.
