What people say
Easy to use, well performing network access
ONCE you installed the ESIM it is easy to buy travel plans in the App. And the ESiM only starts working immediately when you arrive in the country. Very easy! And great network coverage too!
4 star rating
I'm giving a rate of 4 star because sometimes the data connection is not good.
Great connection always
Great connection always, Wishing you all the success 🙌 Thank you
My experience was positive
My experience was very positive but there were some zones where there was no signal, so I cannot assign 5 stars

I bought the eSim service to use on the Channel Islands for a period of 2 weeks. After 3 days, I got no more connection with the eSim service. I wrote an email to customerservice if they could help me. If they could do nothing for me, I asked for a refund for the days I couldn't make use of the eSim service. They replied very quickly and polite why I wished for a refund. I explained that I rather got a solution for the problem, but if a solution was not possible, then I thought it was reasonable to get a refund. The reply was again quick and short: I will get a refund. In short, the service was bad, but quick solution was accurate, although I 'd rather had a good eSim connection

Dear Natasa, We are sorry to hear that your internet speed was slow. Sluggish data performance often occurs due to temporary local tower congestion or lower signal coverage in specific areas. 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 switch to a faster local line.
Unlimited data plan is not actually unlimited
Although they mention reduced speeds after a certain threshold for the unlimited plan, there is actually a gigabyte cap that unlimited users have access to (not mentioned in the time of purchase which is very misleading). After the plan has exhausted the unmentioned cap the eSIM becomes inactive which the company gives no warning about which can becomes very inconvenient for users that are in a place where they do not have access to their regular internet providers.

Dear customer, We are sorry for the confusion and frustration regarding the fair usage threshold on our unlimited plans. Our unlimited data plans operate under a Fair Usage Policy (FUP) to maintain overall network quality; while high-speed data is subject to daily or total thresholds, total service deactivation should not occur without notice. Details regarding our Fair Usage Policy are available on our website, and our support team is always available to review your account details and clear up any questions regarding your plan limits.
Frequent lost connection for 2/3 hours
Stopped working after 3 days
When it works it’s good. But it stopped working after 3 days….nothing helped. So much for unlimited 15 days…… Addition after reply by Ubigi; I’ve only used 441 mb in total during the 2,5 days my unlimited package worked. I’m aware of your fair use policy. My friend encountered the same connection issues at the same time. He uses a Samsung. Different operating system same issue. Maybe a different solution would do the trick?

Dear Gert Jan , We are sorry to hear that your 15-day unlimited plan stopped working after just three days and that troubleshooting did not resolve the issue. Interruptions on unlimited plans can occur if temporary usage limits under our Fair Usage Policy are reached or if the line encounters a tower registration error. We see that you are already in touch with our support team, and we sincerely hope they can help resolve this for you quickly so you can enjoy the rest of your service. Setup and troubleshooting guides remain available on our website whenever needed.
My internet did not work at all
My internet did not work at all when I arrived in the U.S., and I was left stranded at the airport without a connection. Purchasing an eSIM from Ubigi was one of the worst decisions I’ve made. The service failed when I needed it most, and I would like a full refund.

Dear customer, We're sorry to hear about your experience. In cases like this, the issue can sometimes be related to the device setup, such as the eSIM installation, data roaming, APN settings, or network selection, which can prevent the service from connecting properly even after arrival. We have reached out regarding your experience in the hope of making it a better one, including assisting you with your refund request.
Almost Perfect

Dear Swetha, We are sorry that you lacked internet access most of the time and experienced very slow speeds.

Network switching instructions and setup guides are available on our website, and our support team is always available to help troubleshoot your settings and improve connection stability.
Fast, reliable
I used ubigi in Canada
It just works and has a great price
I’ve tried a few of these services and had hit and miss results. However, Ubigi was on point and it was much better than the rest. The reasons? It was easy to set up and more importantly had a low price for top up when I wanted an extra day.
No issues at all using Ubigi
Very easy to use and a great price
Very easy to use and a great price. I will definitely use again in the future.
