Guest User2026-04-24
Very stable network and date. Uses throughout the trip with no glitch. Evwn when I have a flight change and delay with layover or 24hrs. My data lastes throughout until the vwry last day this with juggles of WIFI providws at hotels and relative home. JEasy to use and not complicated though I was worried that I had faced challenges while wanting to top up my data..

I travel to Türkiye, Chile, Argentina and Brazil using this eSIM. The connection and automatically switch to local telco provider upon crossing borders were all very smooth, and data roaming also very smooth. Also they provide a link via SMS, so we can check our data usage anytime we like. Very convenient!
