What people say
Lack in customer support
Lack in customer support: After reactivate the Ubigi e-sim in my car due to a technical issue, the annual subscription could not be restored by customer support. Only solution they offered is to buy a new data plan. Not really customer friendly!

Dear Dani, Thank you for sharing your feedback. We acknowledge the difficulty you experienced regarding the restoration of your annual subscription following the reactivation of your eSIM in your car. Because this is an organic review and we do not have your direct contact details or account email associated with this post, we are unable to look into your specific account or verify what occurred. Setup and account guidelines are available on our website, and if you would like us to investigate this further, please feel free to reach out to our support team with your original account details.

It started out great
It started out great. Coverage was great, but then suddenly it dropped and I couldn’t get it back.
Reply from Ubigi eSIM2026-08-07
Dear Trevor , We are sorry that your connection suddenly dropped after starting out so well. A sudden loss of data access can occur if the device loses registration with the local cell tower, if APN settings shift, or if a data allowance limit is reached. In many destinations, we have multiple network partners available. Network switching instructions and setup guides are available on our website, and our support team is always available to help troubleshoot your connection and get your data back online.

They didn’t respond to my repeated messages about not being able to connect my eSIM until I was days into my holiday. Ugh!

Dear MaryAnn , We are sorry for the delayed response to your messages and that you were left without eSIM support during the first days of your holiday. We understand how frustrating it is to spend vacation time waiting for technical assistance. Step-by-step setup guides are available on our website, and our support team is always available to review your account details and assist you with your line.

Unfortunately there was a lot of moments when we didn’t have any connection in the region where we went.

Dear customer, We are sorry to hear that you experienced multiple connection gaps during your trip. Inconsistent service often happens in regions with varying partner tower coverage or topography challenges. 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 you manually connect to a local carrier with stronger signal coverage in that region.

Connection unstable
The network was horrible. It disconnected every 30 seconds. Every body around me with a "real" SIM, had a stable connection. I really don't understand !

Dear Olivier, We are sorry to hear that your connection was unstable and disconnected every 30 seconds. Frequent dropping can happen when a device continuously struggles to register with a specific local cell tower or encounters an APN configuration error. In many destinations, we have multiple network partners available. Network switching instructions and connection guides are available on our website, and our support team is always available to help you manually lock onto a stable local network line.
It isn't intuitive to use & doesn't work well
It isn't intuitive to use. It doesn't let me use it for data to check my email or make calls on WhatsApp when I'm not connected to wifi.
Reply from Ubigi eSIM2026-08-07
Dear customer, We're sorry to hear about your experience. Issues with using data for email or WhatsApp can sometimes be related to the eSIM setup, data line selection, data roaming, APN settings, or network selection on the device. We have reached out regarding your experience in the hope of making it a better one.
Could never make a good phone call.
Reply from Ubigi eSIM2026-08-07
Dear Mitchell , We are sorry for the poor quality you experienced when making calls. Ubigi provides data-only eSIM services, which means standard voice calls over cellular networks are not supported, and calls must rely on VoIP applications (such as WhatsApp or Skype) that depend on data signal stability. Essential plan details and service specifications are available on our website, and our support team is always available to help answer any questions about our service features or connection performance.
Registration and activation was fast…
Registration and activation was fast and super easy. But There are areas where the esim cannot pick up a signal. So it was difficult having no data for hours. Had to turn it on and off many times.
Data plan stopped working in first 12…
Data plan stopped working in first 12 hours. Online support was too automated and hard to talk with a real person for support. Would not recommend.
Reply from Ubigi eSIM2026-08-05
Dear customer, We are sorry that your data plan stopped working after 12 hours and that you found our automated support system difficult to navigate. We strive to connect customers with human support whenever automated troubleshooting is insufficient. 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 investigate your line performance and assist with your account.
Nearly half of the time no connection.

Dear Ghasan, We're sorry to hear about your experience. Intermittent connectivity can sometimes be related to the device setup, such as the eSIM configuration, data roaming, APN settings, or network selection. It may also be affected by local network coverage, temporary congestion, or conditions with our local network partners. We have reached out regarding your experience in the hope of making it a better one.
Sets my mind at ease
The ease of use is great and the fact that I can use nearly unlimited data without a worry in a far away country.
