Just saw this deal on hotukdeals, which might be useful to our readers.
It is a promotion run by Better Roaming, a company that provides eSIM service. If you scan the QR code below with your phone, you will be redirected to installing an eSIM:
Once activated, the eSIM comes with a 30-day plan including 1GB data. The package is valid at 148 countries, full list here.
It is a pretty good offer (and most importantly free). If you need more packages, you could consider Airalo as well which I’ve been using extensively in the last two years.
