On the other hand, UPeSIM is a platform that allows users to connect to any network without paying more for international roaming fees. So, here you will see a comparison of Holafly vs. UPeSIM, how they work, their coverage, plans, and rates worldwide, among other details that will interest you.

An eSIM is a SIM card that is embedded inside the cellphone and not in the card slot. eSIMs are usually integrated only in newer smartphones, although they’re also available in other devices like tablets and other compatible devices, such as smartwatches.
Holafly is a provider of international virtual chips or virtual cards. Not only is the entire purchase process carried out through its online website store, but also the Holafly cards are easy to set up, and you can use them in different countries worldwide. In the case of the eSIM, you only have to scan the QR code that the company sends you so that you can connect to the internet from your virtual chip.
The best part starts when we talk about their data plans, which for many destinations, have unlimited data. This feature makes them attractive to tourists from all over the world because you don’t have to worry about running out of data.
Whether the eSIM is unlimited data or not, Holafly still allows you to buy top-ups to renew your service if necessary. You don’t need to install a new eSIM because it will be activated immediately the first time you buy it.
Indeed, with Holafly, you’ll have cellular coverage almost anywhere. This is because it connects to the networks with the best coverage in each country, using the platforms of the most important local cellular operators. You’ll have a 4G connection throughout your entire trip to more than 160 destinations! One of the best advantages!
Virtual SIM cards for destinations such as Europe, Spain, Italy, France, and Germany add an Austrian number (+43) at no additional cost. With this, you can call Europe except Iceland, Norway, the United Kingdom, Switzerland, Ukraine, and Turkey. You have a total of 120 minutes to receive and make calls.
To point out, UPeSIM and its data chip for travelers can be a great ally for you. They offer data eSIM, so you can connect to the internet during your trip without worrying about the roaming bill. Moreover, with this virtual chip, you can check your email, use online maps and stay in touch with your loved ones!
To buy, you must use the UPeSIM official app (available for Android and iOS), then you have to choose your trip’s destination, select the eSIM data plan and complete the payment. The eSIM is valid once you activate it.
As for the coverage of UPeSIM, it’s available in more than 27 countries in Europe, excluding Poland, as well as other countries in the world, with more than 77 data plans. You can connect to 3G or 4G / LTE networks as long as you are in a stable cellular coverage area.
But in the limited cellular signal areas, you may not have a stable internet connection. So, if you have a 5G phone and you’re going to use a UPeSIM card, you must disable the 5G network in the cellular settings and select 4G connection quality.
Below there’s a comparative table of Holafly vs. UPeSIM. There you can see added details, such as the compatibility of each of these services with different cellular devices.
| Provider | Technical support | Online shopping | App | Compatibility |
| Holafly | Yes | Yes | Yes, available with Apple | All cell phones, as long as it’s unlocked devices. |
| UPeSIM | Yes | Yes | Yes | iPhone XR, XS, 11, 12, 13, Google Pixel series 3 – 6 and Pro, Samsung Fold, Z Flip, S20, and Motorola RAZR. |
Indeed, eSIM cards are a great way to keep your cell phone and get data plans, no matter where you travel. And although you can also use it for international roaming, this is one of the most expensive options that exist. So, if you go on vacation or travel abroad, make sure you stop by Holafly’s online store first and have your data card ready for when you arrive at your destination.
This depends on the eSIM card you choose. In the case of eSIMs with closed data plans, you can share the internet connection, but for eSIMs with unlimited data, this option is not available.
No, this is only so the eSIM can better capture the signal in the destination country. You just have to ensure your eSIM is active to use cellular data.
The cellphones compatible with the Holafly eSIM are the ones mentioned below:
iPhone XS, XR onwards, iPhone SE 2 (2020)
Samsung Galaxy S20 onwards, Galaxy Fold onwards, Galaxy Note 20 onwards, and Galaxy Z Flip onwards
Huawei P40, P40 Pro, Mate 40 Pro, and newer models
Google Pixel 3, 3rd, Pixel 4, 4 XL, 4a, 5, and newer models
Oppo Find X3 Pro and Oppo Reno 5A
Motorola Razr (2019) and Razr 5G (dual SIM).
