Other brands' "unlimited" plans for 7 days: Ubigi $24.00 (unlimited, 20 GB at full speed, then 2 Mbps); Nomad $25.00 (2GB/day at 4G/5G. 1 Mbps after 2GB); Jetpac $26.99 (first 3 GB every 24 hours at standard network speeds); Holafly $27.50 (unlimited) (prices read 30 Oct 2026).

Every one of these lasts 30 days: 3 GB $3.49, 5 GB $4.29, 10 GB $7.19, 20 GB $15.09. The 30 days start when the eSIM first connects to a network there, so you can buy before the trip.

Yes. You pay on this page and the QR code and a one-tap install link arrive by email: no app and no account. It is data only, with no phone number, so your home SIM keeps your calls and SMS.
Does the Czechia eSIM come with a phone number?
No. It is data only: no local number, calls or SMS on this eSIM. Your home SIM stays in the phone for calls and texts (your carrier's roaming rates apply to them), and WhatsApp, FaceTime or Signal calls run over the eSIM's data. If you need a local number in Czechia, for example for a service that texts a code, buy a local SIM there.
