stable and good signal even in rural areas in Yunnan and in the train. Standard installation.

I’m very disappointed with MicroEsim. I bought a plan and it never worked, even after following all the instructions. There was no customer service available, so I had no way to get help or a solution... See more

Doesn’t work
Doesn’t work, laggy, keeps shutting off. Customer support didn’t help and didn’t compensate. I would avoid and choose other eSIM providers that are reliable

We’re sorry to hear that you were not satisfied with your experience. Our records show that your 5GB Europe eSIM plan was active and more than 4GB of data was successfully used during the trip, which indicates that the service was generally working as expected.
We understand that network quality can sometimes vary between countries and may require manual network selection for the best connection. Our support team shared these steps during your case, and we’re always happy to help if you face any setup issues.
Thank you for your understanding.

Impressive
I had a great experience with the customer service representative. She was very patient and thoroughly walked me through setting up and using my new eSIM, which I was completely new to.

Scammers in Vietnam - Viettel at least
Scammers, in Vietnam - no unlimited data, it is a hard cap. No phone number even though it is stated.
Stay away.

We understand that the Vietnam eSIM you purchased only supports receiving SMS and data, and does not include a phone number. This was also explained on our Vietnam eSIM product page.
We truly appreciate your feedback, as it made us aware that customers might mistakenly purchase the wrong product. Therefore, we have now clearly labeled the functionalities of all our products to prevent such issues from happening again.
Your feedback is invaluable to us, as it helps us continuously improve our products and provide you with a better experience. Thank you again for sharing your valuable input.

Great to deal with
I found Microesim great to deal with from the start. It was my first time using an esim and I ended up emailing them all sorts of stupid questions, to which they responded promptly, and courteously. I have no hesitation in recommending this company.

Couldn't add E-sim and money gone. SCAM!
Got a QR code but it didn't work. Error message said that the code is not valid or has been used already. Adding manually same issue. Customer service said I will get a full refund...let's see how that goes. I most probably got scammed!

Be aware that their unlimited…
Be aware that their unlimited connection after high speed data is consumed is actually not unlimited at all. No matter what they claim it has a hard cap and then it's switched off, although they deny officially that it is what happens and try to claim it just feels like it's not working because it's slow and encourage you to buy a new package, even though you can clearly see the data connection is completely gone. To get any help from customer service is hard, they communicate in machine translated Chinese and are not the least bit service minded. Best to avoid.

Thank you for your feedback. We’d like to clarify that after the high-speed data is used up, the plan provides unlimited data at 128kbps. As mentioned in our description, this speed is mainly for basic internet use, such as messaging and light browsing, and cannot support high-speed activities. Our customer service has explained this clearly, and we appreciate your understanding.
