See what travelers are saying about their Czech Republic eSIM experience. Real feedback from real users to help you pick the best plan for your trip.

“I have bought this esim, not the cheapest but 20GB/30 days plan for my son. The performance is pathetic, barely usable at all. Works only now and then, often struggling to connect, extremely slow even when connected. Customer support zero, they claim response in few hours, byt none received in a day. Waste of money. Waste of time that should had been spent enjoying holidays, rather than dealing with poor quality service provider.”

“I bought this one many times in multiple countries and it always worked”

“Not working. I bought their esim 2 days ago. Emailed them about my issues. Support got back to me actually quickly. I got a 'replacement esim' that one worked for less than 15 minutes. The support person escalated the issue and I'm still waiting for their reply.”

“No data, no support”

“Yeah. absultaly gorgeious and good.”

“i bought an esim from SMARTLINE INC. using a card that i only used there, and after that i received attempts of fraud transactions.”

“It's good.”

“Excellent!
Everything went well and very easy installation.
