Self Assistance - eSIM APN settings for Iphone

Now ensure that the Data roaming option to this line is activated.

Go to: Settings > Mobile Data > under Data plans, select the installed eSIM profile^* > Activate Data roaming.

^*it will appear as “secondary” or under the name you renamed it.

NB: The Data roaming option is now activated only for your Ubigi eSIM profile. This means that you won’t have extra roaming costs as only Ubigi rates will be applied while using the Ubigi cellular connectivity.

In the same screen, select Mobile data network in order to configure the APN (Access Point Name). In the APN field, make sure that mbb is specified. If not, type it in the field.

Bought Ubigi eSim a week begore holiday. Installed it the day before our trip. Was quite straight forward installation. Activated the eSim just before take off from our airport. When we arrived in Japan, it just worked.

Great prices and "just works"

Great prices and "just works", as long as the data roaming setting is turned on for the esim. I have used other esim services, but almost always I end up using Ubigi when I travel.

Easy to purchase and use with clear instructions. I ran out of data during my trip in Japan but it was easy to top off with extra data after I made another purchase.

Everything was very uncomplicated!

Went to Japan recently and wanted to avoid high cellphone bill

Went to Japan recently and wanted to not have a huge cellphone bill. Found out about Ubigi eSim and thought that it sounded great and was easy to use. I got it and boy it definitely lived up to my expectations. It was so easy to set up and so easy to use while in Japan. I didn't have to think about anything it was that easy. I highly recommend it for anyone traveling.

Trustworthy and easy to use!

I booked internet for my trip to Switzerland. I honestly didn’t think the whole process would be this easy. In just a few steps, I had internet for a week, that I could easily activate once I was in the country. All the steps are described online and I had no issues along the way. Also, the internet connection was very good wherever I went. I would definitely recommend Ubigi and I will buy my internet here again in the future.
