Very bad experience for the 2nd time in China
Very bad experience for the second time in China, while in previous experience in other countries (eg USA), all worked perfect.
I went to Beijing the beginning of June, had no connection. I received a mail with apologies that there were outages. In July now, I went to Wuxi and Shanghai, both big cities. Again the networks was not available. I went through all the checks on the Ubigi app to review if I correctly installed the eSIM and they were all ok, still no connection. I could not access any support, the app got stuck? Will not use the eSIM for China ever again.

Dear Sarah,
We're sorry to hear about your experience.
In China, connectivity can sometimes be affected by local network conditions, temporary outages, or regional and regulatory restrictions, even when the eSIM is correctly configured. These factors may impact service availability despite the setup being completed properly.
We have reached out regarding your experience in the hope of making it a better one.
Easy process
Easy process, subscribe, pay, install e-sim then it works immediately without complications.

Weak and unusable connection
Got an esim for Africa. First stop Tanzania and service was terrible. Simply did not work at all. Super slow. Unusable. Emailed customer support and have heard nothing. A true mess. Just pay more and get a better provider.

Dear customer,
We are sorry that your service in Tanzania was unusable and that you have not yet received a response to your email. Signal coverage in parts of Africa can vary depending on local tower density. In many destinations, including Tanzania, we have multiple network partners available. Network switching instructions are available on our website, and our support team is always available to help you establish a stronger connection.
Reliable and mostly fast

Reliable but adds up in expenses if using regularly.
I use Ubigi regularly when I travel. The connection has been consistent and reliable across a variety of destinations and I do recommend it to friends. Sometimes it does seem to be fairly pricey and I would say the use of data seems to vary, it lasts well sometimes and others it drains very quickly. It would be nice to have better discount options for regular customers.

Easy use and connected to the network
Easy use and connected to the network. Do not need any technical knowledge at all.

No network
No network. I have very slow connection in Philippines. I didn’t use my eSIM at all. It’s frustrating

Dear Edna,
We're sorry to hear about your experience.
In cases like this, slow or unavailable connectivity can sometimes be related to the device setup, such as data roaming, APN settings, network selection, or the eSIM configuration. Local network conditions may also affect performance in some areas.

The coverage is great and I. Was very easy to set up before I arrived.

Loses connection frequently &randomly
Bought this for a trip to Japan, so far we've been in a big city (Osaka), and the connection has already been unreliable, it often randomly just disconnects, I haven't really figured out why, sometimes if I toggle the data / SIM on and off, it reconnects again, but sometimes it takes minutes before reacting, really annoying. And this is in a big city where connectivity should be no problem.

Dear customer,
We are sorry for the frustrating dropouts you are experiencing in Osaka, especially having to repeatedly toggle your SIM to restore data. In dense metropolitan areas like Osaka, random disconnections usually happen when a device struggles during automatic handovers between congested local towers. In many destinations, including Japan, we have multiple network partners available. Network switching instructions are available on our website, and our support team is always available to help you lock onto a more stable line.
DO NOT RECOMMEND. was a waste of time & $$
E-SIM didn’t work properly, couldn’t text or receive messages or emails. Also could not get in touch with Ubigi. Would NOT recommend. Very disappointed with this app.

Dear customer,
We are sorry that your eSIM did not function properly and that you were unable to get in touch with us. Please note that Ubigi travel eSIMs are strictly data-only, so traditional cellular texting and phone calls require internet-based apps like WhatsApp or iMessage. In many destinations, we have multiple network partners available. Network switching instructions are available on our website, and our support team is always available to help resolve data connection issues.
Horrible Experience
I’m in Indonesia right now and I bought an esim that is usable for the country. However, I couldn’t use it at all though my esim was activated properly, and at the end I had to buy another esim. I literally thrown away some money.
