4.7 out of 5

I use ZIM often (have already used 6 times)…but

by The Movie Criticsss

this app is super convenient and I use it often. But for some reason the last 2 or 3 times the QR code never works. I have to enter the activation code manually. Inconvenient and it gives me anxiety. It gives me a “no valid data found” error when scanning QR code.

Also. Sometimes I have several hours after purchase to activate. Even though ZIM says it is ready. This also makes me feel like there is a problem

Thankfully it has eventually worked out each time, but it’s unreliable/inconsistent to the extent that i may try another app.

Slow connections

by Paul.reviews

I do appreciate how well ZIM works short term, Unfortunately though, I do tend to use a lot of mobile data for various things, so at a certain point the speed is severely slowed down.

Downgrading the speed of internet to 512 kbps is makes unlimited plans highly not worth it as opposed to other esim providers who don't throttle connections.

The 1gb and 5gb plans and all all work very well though, it kind of depends what you are seeking for internet.
