International roaming is designed to keep you connected the moment you land in a new country. In theory, your phone should basically switch to a local partner network, allowing you to call, send messages, and browse the internet just as you do at home. But in reality, things don’t always go smoothly or work as expected.
In fact, a GSMA Intelligence Survey found that more than 27% of travelers experience roaming-related issues such as “No service” notifications, failed SMS delivery, or data connection problems. This data highlights how common and frustrating international roaming issues can be while traveling abroad.
These issues aren’t random, they often come down to network agreements, overlooked account restrictions, or something as simple as a misconfiguration on your device. Whatever the case, understanding the origin and avoiding the guessing game is the first step towards solving the issue.
In this article, we will take a close look at why international roaming sometimes fails, practical steps you can take to troubleshoot and restore your connection, and the smartest alternative for frequent travelers so that you can avoid the common pitfalls of roaming and stay connected whenever you travel.
What is International Roaming?
International roaming is a mobile service that lets you use your phone abroad without changing your SIM card. It works through agreements between your home carrier and foreign networks allowing your device to connect automatically once you land in another country.
Roaming bridges the gap between your local carrier and a foreign operator. For example, if you are an MTN subscriber from Nigeria traveling to the UK, your phone might connect to a partner network like Vodafone or 02. This connection feels seamless on your end but behind the scenes, your carrier is billing you for using that foreign network’s infrastructure.
But despite the cost, many travelers still rely on international roaming for ease of staying connected instantly, yet this convenience doesn’t always guarantee smooth service. Many face problems like slow data, failed SMS deliveries, or no service at all. Understanding how roaming works is the first step to troubleshooting these challenges and ensuring you stay connected when it matters most.
What Are the Common Reasons for International Roaming Not Working?
International roaming can stop working for several reasons and most of them are easier to overlook than you might think. Below are the most common issues travelers face.
1. Roaming Not Activated
One of the most frequent causes is simply forgetting to actively roam before leaving home. Some carriers require you to enable the feature through your account settings, a mobile app, or by contacting customer support. If this step is skipped, your phone won’t be able to connect to foreign networks no matter how strong the signal is.
2. Unpaid Bills or Plan Restrictions
Mobile operators often block roaming access when there are unpaid bills, low account balances, or restrictions on certain plans. For example, some budget or local-only data plans don’t include international roaming. Without setting up your account or upgrading your plan, roaming services won’t be available.
3. Incorrect APN Settings
Your Access Point Name settings control how your phone connects to the internet. If these settings are missing, outdated, or entered incorrectly, mobile data will not work while roaming. This is a common issue for travelers who switch SIM cards or who haven’t updated their phone carrier settings in a while.
4. Device Incompatibility
Not all phones are built to work with every frequency around the world. If your device doesn’t support the bands used by the local carrier, it may fail to connect entirely. This is especially common when traveling between regions that use different technologies such as GSM and CDMA.
5. Network Coverage Issues
Even when roaming is activated and your device is compatible, you might still experience problems in areas with weak or no coverage. Rural or remote regions often lack strong mobile signals, meaning your phone may show “No service” despite everything being set up correctly.
6. SIM Restrictions
Some prepaid SIM cards and entry-level mobile plans are limited to domestic use only. These restrictions prevent the SIM from connecting to foreign networks, leaving you without service once you travel abroad.
How to Troubleshoot Data Roaming Issues
If your roaming is not working, the good news is that most problems can be fixed with a few quick checks. Here is a step-by-step guide to restoring your connection.
1. Enable Roaming in Your Settings
The first thing is to check whether roaming is turned on for both calls and data. On most smartphones, this option can be found under Mobile Networks or Cellular settings. Without enabling it, your phone will not attempt to connect to a foreign network even if it is available.
2. Check your Carrier Roaming Agreements
Not every provider has coverage in every country. Visit your carrier’s website or contact support to confirm if roaming is supported at your destination. If your operator does not have a partnership with local networks in that country, your phone won’t be able to connect.
3. Manually Select a Network
Mobile phones usually connect automatically to the strongest partner network but this doesn’t always work. Go into your network settings and switch from “”Automatic” to “Manual” mode then choose one of the available networks. Sometimes connecting manually solves the problem immediately.
4. Update Your APN Settings
If calls and texts work but mobile data doesn’t, the issue could be incorrect APN settings. These control how your device connects to the internet. You can usually find the correct APN details on your carrier’s website and enter them manually into your phone’s settings.
5. Restart Your Phone or Reinsert Your SIM Card
Simple resets often fix temporary glitches. Restarting your device or removing and reinserting the SIM card can refresh the connection and allow your phone to register with the local network properly.
6. Contact Customer Support
If none of the above works, reach out to your carrier support team. They can check if roaming is active on your account, guide you through the correct settings, or escalate the issue if it’s a network-side problem.
Even with the right troubleshooting steps, roaming isn’t always a perfect solution. You may still face high costs, slow speeds, or limited coverage depending on where you are. This is why many people now turn to a better option that removes these headaches altogether.
What is the Alternative to International Roaming?
A smarter alternative that is becoming popular among frequent travelers is eSIM technology. Instead of swapping SIM cards when you travel, you can download an eSIM profile and instantly connect to a local or global mobile network. This makes it possible to set up service before or after you arrive at your destination all without visiting stores or dealing with tiny SIM trays.
eSIM data plans are usually far cheaper than international roaming charges, especially for heavy internet use. eSIMs can be activated in minutes, often by scanning a QR code so you are connected as soon as you land.
While the benefits of eSIMs are clear, not every provider offers the same level of affordability, coverage, and ease of use. Many global eSIM services come with hidden costs or limited support, leaving travelers frustrated. This is where Prestmit eSIM stands out, bringing together cost-effective plans, seamless setup, and reliable connectivity that make it a preferred choice for modern travelers.

Frequently Asked Questions (FAQs) About Troubleshooting International Roaming Not Working
How do I activate international roaming?
You will need to enable roaming in your phone settings and request activation from your carrier before traveling. Some providers allow activation through their app while others require you to connect to customer support.
Is roaming more expensive than eSIM?
Yes. International roaming charges are usually far higher than local or regional eSIM plans. Providers like Pestmit offer affordable eSIM data bundles that cost a fraction of standard roaming fees.
Do I need to remove my physical SIM to use an eSIM
No. Most modern smartphones allow you to keep both active. You can keep your physical SIM for calls and SMS while using the eSIM for cheaper data.
What should I do if my roaming data is very slow?
Switch networks manually in your settings, restart your phone, or check your APN configuration. If the problem persists, using an eSIM with a local provider can give you faster speeds.
Is eSIM safer than using public Wi-Fi abroad?
Yes. With an eSIM, your connection runs on a secure mobile network instead of public Wi-Fi reducing the risk of data theft and cyber attacks while traveling.
