Travel eSIM not working abroad: what to check after arrival

A travel eSIM not working abroad can be frustrating after a flight, but deleting the profile should not be the first response. Apple explicitly says not to erase an eSIM as a troubleshooting step unless the network provider directs you to do so. If you erase it, you need to contact the provider for a new eSIM. Apple Support: erase an eSIM

Work through the checks below from the least disruptive step to provider support. After each change, turn Wi‑Fi off and load a website. That tests the cellular connection rather than the airport, hotel, or café Wi‑Fi network. Google likewise recommends turning Wi‑Fi off when checking whether a mobile-data indicator appears. Android Help: fix internet connection problems

Identify the symptom first

What you see	Check first
No Service, Searching, or SOS	Confirm that the line is on, then use Airplane Mode and restart
Signal bars but no webpages	Confirm the data line, mobile-data setting, and the relevant line settings
Only Wi‑Fi works	Turn Wi‑Fi off and retest cellular data
Your home number cannot receive calls or texts	Review the dual-SIM assignment; this is separate from mobile data

On iPhone, No Service and Searching mean the device is not connected to a cellular network. SOS or SOS only means the phone can still make emergency calls through another available carrier network; it does not confirm normal service on your own line or working mobile data. Apple Support: SOS, No Service, or Searching

Step 1: Keep the profile and confirm that the line is on

Open your cellular settings and locate the travel line. It may be labelled with a provider name, a destination, or a name selected during setup. Do not tap Delete eSIM, Delete Plan, or any similar removal option. At this stage, you only need to inspect and enable the line.

iPhone

Open Settings → Cellular or Mobile Data, select the relevant line, and confirm that Turn On This Line is enabled. Apple gives this check for Dual SIM iPhones: if the cellular line is off, turn it on and check service again. Apple Support: review Dual SIM lines

If you bought a travel eSIM before departure, iOS 26 and later may show a Turn On Travel eSIM notification after arrival. Apple documents options to use the travel eSIM alone or keep both the travel and current lines active. Apple Support: use eSIM while traveling

Google Pixel

On a Pixel, go to Settings → Network & internet → SIMs, select the line, and make sure both Mobile data and Use SIM are on. Google lists these as checks for a mobile-data problem. Google Pixel Help: fix mobile connectivity issues

Menu names and available controls on Android vary by phone, Android version, carrier, and service plan. On a non-Pixel Android phone, use the equivalent SIM, mobile-data, and line-enable controls rather than assuming the Pixel path will match exactly. Google Pixel Help: mobile-network settings

Step 2: Make the travel line the mobile-data line

When two lines are active, signal bars can belong to one line while mobile data is assigned to another. Seeing your home carrier’s signal therefore does not prove that the travel profile is supplying data.

On iPhone, go to Settings → Cellular / Mobile Data → Cellular Data and choose the travel line. Apple states that an iPhone uses one cellular-data network at a time. Apple Support: Dual SIM with eSIM

On Pixel, open Settings → Network & internet → SIMs and choose the line for Mobile data under the primary-SIM settings. Google states that only one SIM can be the default for data. Google Pixel Help: use dual SIMs on Pixel

If you do not intend to use your home plan’s data, do not turn on Allow Cellular Data Switching on iPhone without understanding the setting. Apple says that it lets the iPhone use cellular data from both plans depending on coverage and availability. Apple Support: cellular-data switching

Step 3: Check data roaming for the correct line

Do not assume that every travel plan needs the same roaming setting. Follow your eSIM provider’s instructions. If that provider tells you to enable data roaming, enable it for the travel line—not automatically for your home line.

For international travel, Apple instructs iPhone users to check Data Roaming. On a Dual SIM iPhone, open Settings → Cellular or Cellular Data, select the number to modify, then open Cellular Data Options and turn on Data Roaming. Apple Support: international roaming check

On Pixel, the Roaming control allows the phone to send data over other carriers’ networks when it leaves the area covered by the carrier’s networks. Google also cautions that available mobile-network settings vary by phone and Android version. Google Pixel Help: roaming setting on Pixel

Leave roaming off on the home line if you do not want to use that line abroad and have not confirmed its terms. Apple advises contacting the carrier for details about international roaming and possible fees. Apple Support: international eSIM options

Step 4: Reconnect to the network

This does not erase the eSIM or remove its plan. On iPhone, turn Airplane Mode on for at least 15 seconds, then turn it off. Apple recommends this sequence when the device shows No Service or Searching. Apple Support: reconnect to a cellular network

On Android, turn Airplane Mode on, wait 10 seconds, turn it off, and check the connection again. Google provides that sequence for mobile-data troubleshooting. Android Help: toggle Airplane Mode

If that does not resolve the issue, restart the phone. Apple includes restarting in its service-reconnection guidance, and Google recommends a restart as a general step for an Android connection problem. Apple Support: restart for service issues Android Help: restart an Android device

Step 5: Test coverage without forcing network settings

With Wi‑Fi off, look for the mobile-network indicator. If signal is weak or absent, move to a different location or go outside and test again. Google notes that the absence of a data indicator can mean there is no coverage in the current area and recommends trying another location. Android Help: check signal and coverage

Do not force a preferred network type or manually select a network simply as an experiment. On Pixel, the network-type options and their availability can vary by country, carrier, and phone; when 5G is unavailable, compatible Pixels can fall back to 4G or lower networks. Google Pixel Help: network type and 5G availability

Manual network selection is appropriate only when your eSIM provider specifically identifies a network to select. Otherwise, return to automatic selection and complete the line, data, Airplane Mode, and restart checks first.

Step 6: Do not enter a random APN

If the line is enabled, selected for data, and visible on the network, do not paste an APN from an unverified forum. Google explains that access point names help the carrier find the correct IP address and connect the phone securely. Use an APN only when the eSIM provider has supplied the exact values and asked you to enter them. Google Pixel Help: access point names

If settings display a SIM error, save the exact wording or take a screenshot before contacting support. Google’s guidance for a SIM error is to contact the carrier. Keeping the message is more useful than deleting the profile and losing the state you were trying to diagnose. Google Pixel Help: SIM-card errors

Step 7: Update settings, then consider a targeted reset

On iPhone, connect to Wi‑Fi and go to Settings → General → About. Apple says an available carrier-settings update will appear there as an update option. Apple Support: check for a carrier-settings update

On Pixel, Google documents a mobile-network reset at Settings → System → Reset options → Reset mobile network settings. Use it only after checking the line, mobile data, provider-directed roaming setting, and Airplane Mode. Google Pixel Help: reset mobile-network settings

Do not jump straight to a factory reset for an ordinary travel-data issue. The official Apple and Google sequences begin with focused checks of the line, mobile data, Airplane Mode, restarting, updates, and provider support. Apple Support: No Service troubleshooting Google Pixel Help: mobile-data troubleshooting

When to contact support

Contact the eSIM provider if the profile is on, assigned to data, configured according to its roaming instructions, tested with Wi‑Fi off, and still unable to connect after Airplane Mode and a restart. Apple notes that a carrier can check account status, coverage, device blocking, and whether the device has the appropriate data plan. Apple Support: contact your carrier

Include these details in your message:

• the country and city where you tested;
• the phone model and iOS or Android version;
• a screenshot of the line status and the exact error text;
• confirmation that Wi‑Fi was off during the test;
• what happened after Airplane Mode and restart;
• the time of the most recent connection attempt.

If you cannot activate the travel eSIM on an iPhone at all, check the carrier lock. Apple says to open Settings → General → About and inspect Carrier Lock; an unlocked iPhone shows No SIM Restrictions. Apple Support: check whether iPhone is unlocked

Quick answers

Can I switch an eSIM off temporarily instead of deleting it?

Yes. You can turn an iPhone line off in its cellular settings, while Google documents temporary SIM deactivation on Pixel through Use this SIM. That is different from erasing the profile. Apple Support: check whether a cellular line is on Google Pixel Help: turn off a SIM temporarily

Why do I have signal but no internet?

Check whether mobile data and the SIM are enabled, whether that line is selected for data, and whether its roaming setting matches the provider’s instructions. Apple and Google include these items in their cellular troubleshooting and settings guidance. Apple Support: Data Roaming while traveling Google Pixel Help: check mobile-data settings

Should I remove the profile before asking for help?

No. Keep the profile in place and give the provider the results of your checks. Apple specifically advises against erasing an eSIM for troubleshooting unless the provider directs you to do it. Apple Support: do not erase an eSIM for troubleshooting
