Introduction
Buying an eSIM before a trip to Morocco, Egypt or South Africa is now routine. Getting it to actually work when the plane doors open is where travellers get stuck. We asked Lukas of BaobabSIM three practical questions about connectivity on arrival, and his answers point to a pattern: the eSIM is rarely the problem.
Why an eSIM beats a local SIM on arrival
Lukas was direct about his own reasoning. It was "the arrival, not the price." He landed in Morocco in the evening and did not want to spend the first hour of the trip at a counter with his passport, buying a plan whose data he could not check until after he had paid for it. The eSIM was installed before he left and switched on when the seatbelt sign went off.
The second reason was his own number. A local SIM replaces it, and he needs it for bank codes and for messaging family. With an eSIM, the data sits on a second line and his number stays where it is. That is a practical point worth weighing against the often-cheaper local SIM, especially for anyone who relies on SMS verification while abroad.
The four reasons a pre-installed eSIM won't connect
This is the question that generates the most support traffic, and Lukas was specific: "Almost always one of four things, and none of them is a broken eSIM."
1. The line is installed but switched off, or the phone is still using the home SIM for mobile data. This is the most basic check and the most commonly missed. Installing an eSIM does not automatically make it the active data line.
2. Data roaming is off. A regional plan roams on a partner network, so the eSIM line needs roaming enabled. Travellers keep it off because that is the correct advice for their home SIM. The rule flips when you are on a travel eSIM.
3. They test in the wrong country. A Morocco-only plan will show "No Service" in a transit airport in Europe or the Gulf. That is expected behaviour, not a failed installation, but it reads as one.
4. The APN on Android. Some networks need it entered by hand. As Lukas put it, "signal but no internet" is nearly always that.
What people get wrong in the first hour after landing
The core mistake, according to Lukas, is judging too early. "The phone is still searching for a network, they see no bars inside the terminal and decide the eSIM is dead. Give it a minute, look for the carrier name, then open a page; signal bars are not the test."
After that, the usual errors stack up:
- Leaving the home SIM as the data line
- Turning on airplane mode for the flight and forgetting to turn it off
- Expecting calls and texts on a data-only plan
- Not checking before flying whether the plan covers the country they are landing in
That last point matters more than it looks. As Lukas noted, "A local plan and a regional plan look identical on the card until a border is involved."
The product detail that explains the roaming confusion
BaobabSIM's own setup illustrates the point. Their Morocco plans are local plans on Orange Maroc, while Egypt and South Africa are covered by the Africa regional plan, which roams. That means data roaming has to be on for Egypt and South Africa, but the same setting is irrelevant for a Morocco-only plan. Travellers who buy one plan and assume the settings carry over to another country are the ones most likely to hit the roaming issue.
Practical takeaways before you fly
- Install the eSIM at home, but confirm it is set as the active data line before you land.
- Turn data roaming on for any regional plan. Check whether your plan is local or regional before you assume.
- Do not test a country-specific plan in a transit airport. Wait until you are in the destination country.
- On Android, have the APN details ready in case the network requires manual entry.
- Give the phone a minute after landing before concluding anything. Look for the carrier name, then load a page.
- Check country coverage before departure, not after arrival.
For anyone sorting out connectivity for a multi-country trip, the distinction between local and regional plans is the single detail most likely to determine whether the first hour goes smoothly. BaobabSIM's help centre covers install, activation and the line-will-not-connect scenario, and their contact page routes to a human rather than a bot.
