Improved general UX and bug fixes

Unfortunate problems, deteriorated service

Made purchases in 2024 with no problems. However 2025 July, I had problems purchasing a new eSIM, it was cancelled twice because of local operator issues. Also activation of eSIM wasn’t so smooth, had to restart device, manually select the operator so on. And now trying to top up the eSIM and getting errors again. It’s a shame the service deteriorated since last year dramatically. Also the data speed struggles, WTR is provider and so slow generally where there should not be a speed limit I was told, my partner through other provider 1Global using the same local network Turk Telecom has no issues next to me. At least the support team is trying to help and solve the problems but would be great if they solved these issues and made things easier, smoother and more reliable.

Latest version 4.0.2 crashed

I just install the latest version 4.0.2 of n an IPhone (IOS 18.5) and the app open and close immediately

Scammed me with no response

Was a avid user of the app but I bought an eSIM the other day and it told me it hasn’t worked an the system didn’t put it through so I re bought it and got a very confusing error message. But then the money was taken out of my account both times. I was trying to do this before my flight and had to just wait until I got I got the country and sort something out then. I was automatically referred to a chatbot that just didn’t respond and then closed the chat. Several hours later I then got an email saying the eSIMs came through after they said there was an error, I have emailed them as per their refund policy and haven’t heard anything back but will update IF I ever do . Really disappointing as this was my go to eSIM app bu

Data scam

I just landed in Turkey and only used Google Maps to navigate to my resort, yet somehow, I’ve already used 2GB out of my 20GB allowance. This makes no sense! Back in the UK, I stream movies and series regularly, use tons of data, and never go over 30GB in a whole month. Something about ZIM eSIM’s data tracking feels completely off. If you’re considering using this service, think twice it doesn’t add up, and you might burn through your data way faster than expected. Definitely wouldn’t recommend.

Stopped working

My India plan worked for 3 days then stopped. The only way to contact ZIM is through their chat with very long waits for each reply and requiring WiFi. I’ve ended up getting a new sim with Yo which works fine.
