Real, verified reviews from eSIMfly travelers across 200+ destinations. Every review is tied to an actual purchase — so you can see exactly what to expect before you buy.
Generally works ok across England but sometimes loses connection despite showing full signal and you have to look for WiFi to get it working again.
Response from eSIMfly
Sorry for the inconvenience. This can happen when the phone automatically jumps to an unsupported local network, even if it still shows full signal. Please turn off automatic network selection and manually choose the supported network in the UK. After that, restart mobile data or the phone, and the connection should stay stable. Our support team is also available if you need help with the correct network settings.

Sorry to say, it has been a great disappointment to me. In the first place I bought the SIM in the mistaken belief that eSimFly used the Megafon network in Tajikistan, as I read an article listing them as an eSIM supplier that did. Not so! The sim uses the much more limited-reach Zet-Mobile, which wouldn't have served me on my imminent journey into the Pamirs anyway. It should have been of use for these days in Dushanbe though, had I been able to achieve any internet connection at all.. but I haven't.. niente.. nada. I've followed every bit of advice in the Installation guide provided and tried all the different activation techniques, and entered the LTE set up data I found online courtesy of wikisim.. but nothing has made an iota of difference. It's the first time I've been quite unable to get an eSIM working and in one of the most difficult places imaginable to be without the full set of Google tools.. (maps, translate, lens and web/app access..) I can't find any 'help' facility on the eSimFly app or website so am at an impasse. Thank god I managed to buy a physical Megafon sim today from their main store in Dushanbe and am finally able to function again. Wish I could get a refund on the eSimFly sim I bought, with it's still untouched data, but that doesn't seem to be an option either.. I wouldn't be writing any of this here had I found a way to speak to eSimFly and tell them that I've been without any connection for 6 days now...

Dear customer, We are very sorry to hear about your experience, especially being without internet during your trip. We fully understand how difficult this can be when travelling and relying on maps, translation and other important apps. For Tajikistan, our eSIM is intended to work on the MegaFon network. In some cases, the device may automatically connect to another local network that is not supported or has weaker coverage. When this happens, the eSIM may show no data connection even though the plan is active. The usual fix is to turn off automatic network selection and manually select MegaFon from the mobile network settings. We are sorry that this was not clear enough during your setup. We also want to clarify that we do provide support by email and WhatsApp, and we normally respond quickly. Please contact us with your order details and we will check your eSIM usage, connection status and refund options since you mentioned the data was still unused. Again, we apologize for the inconvenience and we appreciate your feedback. We will use it to make our Tajikistan setup instructions and support contact information clearer for future customers.

the issue was the phone´s automatic network selection - disabling it and choosong vinaphone manually keeps the connection stable
Istanbul esim
During my stay in Istanbul, I used an eSIM throughout the entire trip, and it worked perfectly from start to finish. The setup was easy to complete at home, and as soon as the plane landed, I was connected without any hassle. No searching for local SIM cards or waiting in lines at the airport, which was a big relief when I saw people heading toward different operators at the airport to get internet access. The coverage was very good, both in central areas like Sultanahmet, Beyoğlu, and Kadıköy, as well as when I traveled further out in the city. The internet was fast and stable, making it easy to use Google Maps, book transportation, and stay connected via WhatsApp and social media. I was also able to stream without any problems. What I appreciated most was how reliable everything felt—no unexpected interruptions and no worries about roaming charges. Overall, the eSIM experience made the trip smoother and more relaxing, and I would definitely recommend using an eSIM to others traveling to Istanbul. It’s a simple choice that truly delivers.
