Dear Wassim , We are sorry for the unreliable connection and frequent downtime you experienced in Djibouti despite following our recommended steps.

Network switching instructions and connection troubleshooting guides are available on our website, and our support team is always available to help ensure your line stays stably connected.

Excellent eSIM provider
Easy installation and use, very reliable connection, very fair plans and price. Perfect for my travels use.
Affordable and easy to use
Affordable. Easy to use. 4.5 stars. I got some inaccurate information from their AI based customer service, (although quick response time) otherwise it would be 5 stars. Bought it for Norway and it worked great!
The connection was good but it was not…
The connection was good but it was not easy to connect e-sim. The app said it would be done automatically and it was not. I had to ask for help and they sent a qr and solved it, but I had to use my physical card and that was expensive.

My plan was unlimited however it throttles down after 30 gigs. They don’t advertise it as such … very deceiving , won’t use this service again.

Dear Sarkis , We are sorry for the disappointment regarding the speed reduction on your unlimited plan after 30 GB. Our unlimited data plans operate under a Fair Usage Policy (FUP) to prevent network congestion, where high-speed data transitions to reduced speeds after reaching specific usage thresholds. Full details regarding our Fair Usage Policy are available on our website, and our support team is always available to answer any questions about our plan structures and terms.

Terrible experience
Went to to the isle of man for the TT and got this esim to use while I was there, didn't work at all on my Google pixel 10

Dear customer, We are sorry that your eSIM did not work on your Google Pixel during your trip to the Isle of Man for the TT. Unexpected setup failures often stem from missing APN profile configurations or disabled data roaming toggles on specific Android models. Step-by-step installation and Pixel setup guides are available on our website, and our support team is always available to walk you through device configuration for future travels.
Weak connections throughout usage
Weak connections throughout usage. Took a long time to load anything on phone. Probably use a different eSIM provider in UK next time. Very disappointed.
Reply from Ubigi eSIM2026-08-06
Dear customer, We are sorry for the weak connection and slow loading times you experienced during your stay in the UK. Sluggish speeds are usually caused by local network congestion or being connected to a weaker partner cell tower in your immediate area. In many destinations, including the UK, we have multiple network partners available. Network switching instructions are available on our website, and our support team is always available to help you select a faster local network line.
Very easy to use
Easy to use and works correctly most of the time.
Too slow
Although its unlimited traffic, 5.72 mbps is just too slow :(

Dear customer, We are sorry for the disappointing connection speeds of 5.72 Mbps during your usage. Slower data speeds are typically caused by local network coverage variations, distance from nearby cell towers, or temporary signal congestion in your immediate location. In many destinations, we have multiple network partners available. Network switching instructions and coverage information are available on our website, and our support team is always available to help you select a local partner network with stronger coverage.
