Every year, thousands of Israeli travelers return from abroad with shocking phone bills, or with error messages that prevented them from staying connected exactly when they needed it most. Many of these mistakes repeat themselves over and over — and some can be easily avoided.
Mistake 1: Installing a foreign SIM without turning off data roaming first
This is perhaps the most serious mistake. When you switch SIMs abroad, your Israeli SIM remains in your device — and it may continue using data roaming if you didn't turn it off before your flight. Result: a bill with astronomical figures. The golden rule: Turn off data roaming on your Israeli SIM while still in Israel, before you leave.
Mistake 2: Buying a local SIM card without checking first
Many tourists buy the first SIM card they find at the airport, without comparing prices or plans. In Thailand, Canada, or Brazil — prices can vary greatly between operators. Our tip: research online in advance which operators are best for your destination, and which plans offer the best value.
Mistake 3: Not checking network coverage before traveling
Not every SIM works everywhere. If you're traveling to remote areas — whether in Canada, Kazakhstan, or the Netherlands — check the operator's coverage maps in advance. There are places where certain SIMs won't work at all, or will only work on slow 3G.
Mistake 4: Forgetting to install your eSIM before your flight
If you choose an eSIM, you need to install it when you have a good internet connection. Many travelers arrive at their destination — whether it's Brazil, Qatar, or the Czech Republic — and try to install an eSIM there using poor-quality public Wi-Fi. The solution: Install the eSIM at home, by scanning the QR code, before you leave Israel. You can activate it anytime abroad.
Mistake 5: Not turning on "Airplane Mode" during your flight
This isn't a mistake that results in huge bills, but it's annoying. If you forget to turn on airplane mode, your phone will search for networks the entire way, which drains your battery.
Mistake 6: Not checking SMS and call rates
Many tourists focus on data and forget that phone calls and SMS can be very expensive abroad. Check your plan's call and message rates in advance — especially if you plan to talk with family in Israel.
Mistake 7: Not saving your Israeli SIM information as backup
Before you switch SIMs, save your Israeli SIM phone number somewhere (in your phone, in a message to yourself, in an email). If you need to contact someone in Israel who only has your Israeli number, you'll have the information at hand.
The bottom line
Smart browsing abroad isn't rocket science. Plan ahead, turn off data roaming, choose your SIM or eSIM carefully — and enjoy your trip without being burdened by phone bill worries. Whether you're in Canada, Thailand, or Israel, proper preparation is the key.
