You cross a border, glance at your phone, and it still says "No Service." If you're travelling through several countries, this happens more often than you'd think. The short answer: right after a border crossing, your phone is usually still searching for a network in the new country, and in many cases toggling Airplane Mode or reselecting the network brings it back. That said, there are other possible reasons too — the country may not be included in your plan, or your data allowance may be running low. This guide walks through the checks in order, so you can work through them calmly even on a moving train or bus.
- Losing signal right after a border can last several minutes
- The first thing to try is toggling Airplane Mode
- If it doesn't come back, check your covered countries and remaining data
- Review which line is used for data, and your roaming settings
- A little prep before you leave saves stress on the day
It's normal not to connect right away after crossing a border
The first thing worth knowing is that losing signal just after a border crossing isn't unusual. An eSIM works by connecting to a network available where you are, so when the country changes, your phone has to search for a network in that new country. That handover can take a few minutes — and sometimes a little longer.
This is especially true when you cross by train, bus, or car. Those routes often pass through tunnels, mountains, and open countryside where coverage is patchy, which makes the switch slower. Quite often, if you check again once you reach a border station or a rest stop, you'll find it reconnected at some point along the way. "No service right after the border" doesn't mean something is broken, so it helps to give it a little time before you start changing things.
Don't delete your eSIM profile on the spot just because it isn't connecting. Once deleted, the same profile often can't be reinstalled, which can make recovery much harder. Treat deletion as a last resort and start with the settings checks instead.
Common reasons for no service or no connection
In practice, the causes fall into three groups: waiting on the network handover, a settings issue, or something about the plan itself. Look at what your screen is showing right now and start with the row that matches — it's the fastest way to narrow things down.
| What you're seeing | Likely cause | First thing to try |
|---|---|---|
| Still shows "No Service" | Phone is still searching for a network in the new country | Turn on Airplane Mode, wait 30 seconds or so, turn it off |
| Bars are showing but nothing loads | A different line is set as your data line | Check which line is selected for mobile data |
| Only this one country won't connect | The country may not be included in your plan | Check your purchase details and the covered-country list |
| Suddenly slow, or stopped | Speed can change based on remaining data or plan conditions | Check your remaining data and plan terms |
| Only certain apps are misbehaving | An app-side issue, or local network congestion | Try again at a different time or location |
Keep in mind that speed and stability vary with local network conditions, coverage in that area, your device, and how busy the network is at that hour. Near borders and in mountainous areas, the same plan can feel weaker than it does in a city.
Checks you can run while travelling (in this order)
Here's the bottom line: working from the top of this list will resolve or isolate most cases. Wait about 30 seconds after each step before moving on — it makes the results much easier to read.
1. Turn Airplane Mode on, then off
This is the simplest fix and often the most effective. Turn Airplane Mode on, wait 10–20 seconds, then turn it off. Your phone will search for networks again and may pick up the new country's network. If it doesn't come back immediately, give it another minute or two.
2. Make sure the eSIM is the line used for data
If you're running both your home-country line and the eSIM, your phone may still be set to use the home line for mobile data. Open your mobile data (cellular / mobile network) settings and confirm the eSIM is selected as the line for data. When you have signal bars but pages won't load, this is very often the reason.
3. Check your data roaming setting
An eSIM used abroad may require data roaming to be switched on for that line. Check that data roaming isn't turned off under the eSIM's line settings. At the same time, it's worth leaving data roaming off on your home-country line so you don't pick up charges you didn't intend.
4. Select a network manually
If automatic connection isn't working, switch network selection from automatic to manual and pick one of the operators listed. If that one doesn't connect, try another — and set it back to automatic afterwards, so your phone switches more easily as you continue travelling. The search takes a little time, so this is easier to do while stopped or once you've arrived somewhere.
5. Restart your phone
If nothing has changed so far, restart the device. It's a simple step, but it forces the whole network-acquisition process to run again, which can push the handover through. The display may not come back right away after a restart, so wait a minute or two before checking.
6. Check covered countries and remaining data
If your settings look fine, turn to the plan itself. Three things to confirm: whether the country you're in is covered, whether you still have data remaining, and whether your validity period has ended. You can review the plan you bought from My Account. Covered countries and usage terms can differ by country and region, so it's worth cross-checking the current listing on the eSIM comparison page as well.
If it still isn't working
At this stage, the quickest route is to go back to the setup steps and your device's compatibility. Work through these in order:
- Is the profile actually enabled? Even when installed, the line has to be switched on to connect. Check that the eSIM line is turned on in your settings.
- When activation starts: how the start of usage is counted can differ between plans. Check the details provided at purchase.
- Is your device supported? The eSIM-compatible device checker lets you confirm your model and whether it's carrier-unlocked.
- Revisit the setup steps: the setup guide covers everything from installation to switching over once you arrive.
- Symptom-by-symptom fixes: our troubleshooting page lists what to check for each situation.
If you've been through all of this and nothing has improved, it's usually faster to get in touch than to keep changing settings. Telling us which country you're in, when it started, and exactly what your screen shows helps us sort it out quickly.
Prep that makes border crossings easier
The single best way to reduce stress on the day is to get everything set up while you're somewhere with a stable connection. Setting things up once you're already moving can be frustrating when the signal keeps dropping.
- Install before you leave: tap the setup link you received and follow the on-screen steps to add the eSIM. In most cases you can wait until you arrive to switch the line on — just follow the instructions provided at purchase.
- Save the covered-country list: a screenshot means you can check it even with no service.
- Make maps and tickets available offline: downloading offline maps and saving your ticket screens makes the wait during a handover much less stressful.
- Agree on how to stay in touch: decide with travel companions or your accommodation how you'll reach each other, while you still have a connection.
- Turn roaming off on your home-country line: check this before departure to avoid unintended usage.
What to know about a data-only eSIM
Bloomy eSIM is data-only. This is an easy point to misunderstand, so we'll be straightforward about it: what you don't get is calling and texting with a phone number (voice calls and SMS). App-based calls that run over data — WhatsApp, Messenger, FaceTime and similar — work as usual. So you can still stay in touch with family and travel companions through those apps.
On the other hand, you'll need another option for the moments that require SMS verification or a phone number — a border station, a local transport service, and so on. If you want to keep your home-country number reachable, one common approach is to keep your home line for calls and texts while using the eSIM for data. If you specifically need a plan that includes a number, check what's available before you travel.
Multi-country plan or country-by-country plan?
In short: if you'd rather not touch your settings every time you cross a border, a multi-country plan tends to suit you better. If you're staying in only a couple of countries and spending a long time in each, country-specific plans often make more sense. The signal drop at each border is hard to avoid either way, but a plan covering multiple countries at least spares you swapping eSIMs country by country.
| Multi-country plan | One plan per country | |
|---|---|---|
| Good for | Three or more countries in a short trip / lots of travel days / not wanting to change settings repeatedly | Staying in one or two countries / a long stay in a single country / a fixed, known itinerary |
| Not ideal for | Staying in essentially one country | Itineraries that change country every few days |
| Watch out for | Whether every destination is on the covered list | The hassle and timing of switching between plans |
Which one fits depends on your itinerary. If you'd like the full picture on coverage, trip length, and how to think about data, our guide to choosing a multi-country eSIM for trips across two or more countries lays out what to weigh up. If your destinations are already set, the comparison page lets you search by country, data amount, and number of days.
In summary: Airplane Mode first, then coverage and data
Losing signal after a border crossing is usually just the network handover in progress. Toggle Airplane Mode, check which line is used for data, check data roaming, try selecting a network manually, restart — and if it still hasn't come back, check your covered countries and remaining data. Keeping that sequence in mind will save you a lot of time on the road.
Before you leave, the things you can do are: install from your setup link, confirm the covered countries and usage terms, and get set up so you're fine offline. As a next step, check plans for your destination on the comparison page, or clear up any questions in advance on our FAQ.
