Picture this: You’re on vacation and your Ubigi eSIM suddenly stops working. You know that there are still plenty of days left on the plan, so why would it not work? Chances are, you’ve reached your data limit. Thankfully, you can get back online by topping up your eSIM. Follow along to learn how to do that and if buying top-ups is the best option for you.

Ubigi eSIM top up

What is an eSIM top-up?

Topping up your eSIM data plan simply means adding more data to your current plan. Doing so allows you to keep using your eSIM without having to buy a new one. This applies only to fixed-data plans. Ubigi’s unlimited plans don’t require a top-up since there’s no limit on how much data you can use.

The upside to topping up your Ubigi eSIM data plan is that it’s quicker and easier than having to purchase and set up a new eSIM. That said, top-ups aren’t free and often cost the same as a new plan, so while they are convenient, they won’t save you any money.

How to top up your Ubigi eSIM?

You can purchase a top-up for your Ubigi eSIM on the Ubigi app or through the Ubigi website. The steps for both are nearly the same:

  1. Open the Ubigi app or the Ubigi.me user portal on your browser.
  2. Log into your Ubigi account.
  3. Tap on the top-up symbol next to one-off data plans.
  4. Choose the amount of mobile data you want to add to your plan.
  5. Make a payment to complete the top-up.

Once done, data should be added to your eSIM immediately. Notably, you can access the Ubigi app for top-ups even without data left on your plan, so if you run out, you don’t need to look for the nearest public WiFi hotspots just to add more data.

How much does a Ubigi top-up cost?

The price of Ubigi top-ups is exactly the same as the price of new eSIM plans. The price depends on the data allowance you need and where you’re going to be using your eSIM. 

For reference, let’s take a look at the price of Ubigi’s eSIM plan for the USA, but keep in mind that the prices may differ slightly depending on your destination.

  • $2.90 for 500 MB
  • $4 for 1 GB
  • $7 for 3 GB
  • $9 for 10 GB
  • $26 for unlimited data for 7 days
  • $28 for 25 GB
  • $45 for 50 GB
  • $65 for unlimited data for 30 days

The prices are similar for a majority of the most popular destinations covered by Ubigi, though slight variations are to be expected.

Disclaimer: The prices are accurate as of March 28, 2025, and are subject to change.

Is an unlimited data eSIM better than buying top-ups?

As a general rule, fixed-data plans are great if you don’t need a lot of data, while unlimited plans are better if you’re a heavy data user. So, if you find yourself constantly topping up your eSIM plan, it might be cheaper for you to get an unlimited plan instead.

To give you a more accurate answer, let’s compare Ubigi’s USA plan with Holafly, one of the top unlimited data eSIM providers on the market today.

Ubigi eSIM for the USAHolafly eSIM for the USA
$2.90 for 500 MB for 1 day$6.90 for unlimited data for 1 day
$4 for 1 GB for 7 days
$7 for 3 GB for 15 days
$9 for 10 GB for 7 days
$14 for 10 GB for 30 days
$26 for unlimited data for 7 days$29.90 for unlimited data for 7 days
$28 for 25 GB for 30 days
$45 for 50 GB for 30 days
$65 for unlimited data for 30 days$74.90 for unlimited data for 30 days

With Ubigi, you’re better off buying an unlimited data plan if you need more than 23 GB for 7 days or more than 60 GB for 30 days. If you’re sure you’ll need less than that, a fixed-data plan will end up being more cost-effective.

Holafly’s unlimited data plans for 30 and 7 days are slightly more expensive than those from Ubigi. That said, Holafly will be cheaper if you need an eSIM for any other number of days except 7 or 30. So unless Ubigi’s offerings exactly match your holiday duration, Holafly will usually be the more affordable option for unlimited data.

It’s worth noting that Holafly allows you to pick any number of days in the range from 1 to 90 for its plans. This allows you to match your eSIM plan exactly to your stay abroad and avoid paying for any days you don’t need.
