For most travellers, yes, if your phone supports eSIM. Czechia plans start at $3.49 for 2 GB, and the longest lasts 365 days, which suits long stays and repeat visits. If your home plan already covers Czechia at no extra cost, you may not need one.

Czechia eSIMs on MobiMatter run on O2, Vodafone, and T-Mobile; 5G plans are available on O2 and Vodafone. O2 carries the most plans. Each plan names its network, so you choose your carrier before you buy.
