When we travel, we want to minimize the possibility of encountering any problems or inconveniences during our stay abroad. One of the most common problems is related to connectivity, especially if we haven't previously checked with our mobile provider to see if any specific settings need to be activated.
To avoid this, one solution many travelers have opted for for years is the eSIM. This type of card allows you to connect in a large number of countries abroad at a much lower price compared to traditional roaming charges. Furthermore, it has the advantage of being 100% digital.
In this article, we'll tell you about the main problems you might face if you choose this solution, how to solve them step by step, and why Blink eSIM is the best provider you can trust for all your needs.

Common problems faced by travelers with eSIMs
eSIM cards don't usually cause many problems for their users. When issues do arise, they're most often due to a problem during activation or related to connection speed. Luckily, everything has a solution, and in this article, we'll help you with that. Below, we'll show you the most common problems you might encounter:
- Activation problems: The most common error occurs when, after installing an eSIM, you cannot activate it correctly before traveling or upon landing. This happens when the activation code doesn't work or the installation is incomplete.
- Connection problems: Another common problem occurs when you arrive at your destination and your phone doesn't connect to the network. This usually indicates that the profile is not active or is not configured correctly.
- Speed issues: Speed issues are another common problem. They can be caused by multiple factors, such as having a large number of applications open in the background.
- Device incompatibility: Everything may be configured correctly, and the provider may not be responsible for the problem you're experiencing. The first thing you should check is that your device is compatible with this technology.
- Geographic restrictions: Remember that not all providers offer connectivity in every country. This is another check you should make to avoid problems upon arrival.
How to troubleshoot eSIM activation problems
There are different ways to resolve problems depending on the specific issue you're experiencing. In this section, we'll focus on activation problems. To resolve them, remember to follow these steps:
- Activation code: The first thing you need to do is make sure you've correctly entered the activation code you received via text message and that you've scanned the QR code properly. One of the most common reasons for this type of error is when the QR code has expired, so you'll need to request a new one.
- Turn airplane mode on and off: Many SIM cards require your phone to toggle connections on and off to function. Turn airplane mode on and off to see if that resolves the issue.
- Restart your smartphone: If you've already tried everything above, there might be a background process preventing your card from working correctly. In this case, restarting your device will solve the problem.
- Check the installation of the profile in question: make sure the profile is correctly installed in the settings menu.
- Does your provider have coverage in that country? As we've already mentioned, one of the most common mistakes we make that prevents our card from working correctly is when we sign up with a provider that doesn't have coverage in that country. This is one of the first things you should check.
How to troubleshoot eSIM connectivity issues
When connectivity problems occur, it's assumed the SIM card is already properly activated. Therefore, the issue is with your smartphone being unable to detect the SIM card. If you're experiencing connectivity problems, we recommend following these steps.
The first thing you need to do is access your smartphone's connection settings. The path may vary depending on the brand, but it's always found within the general settings. Make sure your smartphone is configured to manually select the network.
If you've already checked that and it's still not working, you need to reset your network settings. You'll find this option within the general settings of the network in question, with a message similar to "Reset network settings."
If you've done both and still can't connect to the network, you'll need to reinstall the SIM card profile. First, delete the existing profile and contact your service provider to request a new QR code. Follow the instructions step by step, and you'll be able to activate and use your SIM card normally.
Finally, make sure you're in an area with coverage from that operator. As we've mentioned repeatedly, this is one of the most common oversights that can cause problems with your connection.
Troubleshooting data speed issues
The connection may be active and the card may be working correctly, but we may still be experiencing speed issues. These problems can be intermittent or persist throughout the trip. In either case, it's important to keep the following tips in mind to troubleshoot them.
- Signal strength: Check that you don't have a stronger signal in other nearby locations, especially if you're indo
- Switch between 4G and 5G networks: From the data settings menu, you can switch between 4G and 5G networks. This can significantly improve your connection speed.
- Do you have apps running in the background? While it's not something you usually think about, background apps can actually consume data. Close them all and restart your device to check your actual speed.
- Have you used up all your data? If you don't have an unlimited data plan, you'll have a maximum amount of data you can use. Once you reach that limit, your speed will likely decrease considerably. Check with your provider to see if you have the option to add more data to your plan so you don't run out of service.
Troubleshooting device compatibility issues
We've reached one of the most critical issues we might encounter. Up until now, any of the problems we've mentioned could be resolved if we knew how. However, when we run into compatibility problems, there aren't many options for improving the situation.
The first thing you should do is make sure your device is compatible. Not all Apple or Android devices are. Therefore, contact the manufacturer or consult this list ..
Secondly, make sure your device software is up to date. In many cases, problems arise because we have an outdated system.
Finally, the only thing left to do is check the eSIM settings on your device. You should make sure the card is not only installed but also active.
