The esim worked well. Internet connection was very good, even in the mountains. Although the setup instructions could be a bit clearer. I install the esim before going abroad, and wasn't sure whet... See more

Affordable eSIM
Affordable eSIM with an excellent data only package that I used in Turkey. Network signal was good and reliable. Would definitely recommend to users.
Brilliant ESim
Great sim and great offers to suit your needs.
This was exactly what I needed to stay in contact with my family whilst recently away.
Also, came in handy when I needed the Internet to find my way round using Google Maps.
Would defo use again in future.

Fantastic ESIM
Fantastic ESIM, worked as soon as I landed, just make sure to have phone settings correct - mobile data on etc. And the price was ridiculously low compared to others, especially for 30 days. Would highly recommend!!! Thanks WorldSim, glad I clicked your ad!

6 month pro esim never worked
Paid for 6 month pro esims and never worked properly.
Tried in Portugal and could not get data to work, reported when back with no response.
Now in Indonesia and still issues, managed to use chat on 3rd and all their advice failed; tried again today and now they say out of data and to top up!!
They sent screenshot showing usage whilst at home and esim turned off. Never had an issue with recognised providors so will go back and lose the calls availability not that it worked with Worldsims
Easy to use and worked as described
Easy to use and worked as described. ⭐️⭐️⭐️⭐️⭐️
Fast and reliable support
The sim card works well in the countries I've been so far, - the prices are as declared. Connectivity depends on carrier, however no issues experienced.
The support is reachable rather quickly and responsive , - with any required clarification.
Rapid response by a human
Rapid response by a human, Kevin was clear and helpful

Very great website for esims internationally. Very easy to use.
I would recommend this 100%.
Nothing but good things about Worldsim.
I have been using Worldsim for YEARS.
I bought my first Worldsim card on an aeroplane from a duty free magazine because it seemed revolutionary at the time - a sim card that I could use overseas without having to chop and change - who'd have thunk it??
Back in the day, they used to have phone support, and I will be honest, I miss that, but the chat function is super responsive.
There was one glitch with VOLTE in the US, but even that got resolved and I am still happily using Worldsim.
This sim has been reliable and my go-to. I know what I have on my account and I know what I am spending as I can track it in the online account - it's a bit tricky but once you get the hang of it, it is plain sailing.
My friends and family are very are of how to use the number, don't call me, I'll call you kind of thing. You just need to teach your people not to call unless they have deep pockets. In an emergency, of course, just pick up the phone but the UK looking number is deceptive and is likely to get people into trouble with their bills as it charges as an overseas/premium
Other than that - brilliant!
