What are the advantages of eSIM over a physical SIM card?+
eSIM advantages over a physical SIM card include instant activation via QR code, no plastic to carry or lose, and the ability to store multiple carrier profiles on one handset. The difference between eSIM and SIM card is that physical SIM vs eSIM comes down to hardware: one is embedded, one is removable. HelloRoam eSIM connects to 212+ networks across 185+ countries. You can activate a travel plan from home before your flight and switch between countries without setting foot in a phone shop.
Is eSIM better than a physical SIM card for travel?+
Is eSIM better than a physical SIM card? Yes, for most travellers. It installs over the air with a QR code scan, so there is no card swap, no store visit and no nano SIM card to misplace. eSIM compatible phones include iPhone XS and newer, most Samsung Galaxy S20 and newer models, and Google Pixel 4 and newer (some Pixel 3 and 3a phones work too, depending on where they were bought). HelloRoam eSIM plans start from £0.77 and cover 185+ countries, making it a strong option for travel. Physical SIMs still make sense for phones made before 2018 or destinations with limited eSIM carrier coverage.
Should I get an eSIM or a local SIM for travelling to Europe?+
eSIM works well across Europe. Major carriers including EE, Three, and Vodafone all support it. A local SIM in Barcelona or Paris may cost less per GB, but it requires an in-person purchase and often a wait for activation. HelloRoam eSIM activates before you land and skips all of that. For any trip under three weeks, the convenience easily outweighs the slight price difference.
Can I switch from a physical SIM to eSIM?+
Switching from a physical SIM to eSIM is straightforward with most UK carriers. Contact EE, Three, Vodafone, or O2 through their app or customer service and request an eSIM transfer. You will receive a QR code to scan, which installs your digital profile. Your physical SIM stops working once the eSIM activates, so confirm the transfer is complete before removing your old card.
Is eSIM more secure than a physical SIM card?+
eSIM is more secure than a physical SIM because no one can remove it from your handset or swap it into another device. Your HelloRoam connection stays locked to the phone you installed it on. A physical SIM slides out in seconds and fits into any compatible phone, so a stolen card can be used in another handset. HelloRoam eSIM profiles use the GSMA encryption standard.
Does eSIM affect signal strength or data speeds?+
eSIM does not affect signal strength or data speeds. Both eSIM and physical SIM connect to the same cell towers using identical technology. Your actual speeds depend on the carrier network, your location, and your plan.
Can I switch back to a physical SIM after using eSIM?+
Switching back to a physical SIM is possible. An eSIM profile is not transferable between devices the way a physical SIM is. To move back, there is no need to remove the eSIM. Put your physical SIM back in if you took it out, then switch your mobile data line to it in your phone's settings. Contact your UK carrier if you need help. Always complete any transfer before resetting or selling your old device to avoid losing access to the profile.
Is eSIM or physical SIM better for international travel?+
eSIM vs physical SIM for international travel comes down firmly in favour of eSIM. HelloRoam eSIM connects you to 212+ networks across 185+ countries from £0.77, making it the better option for most international travel. You activate before landing with no store visit and no SIM swap needed. Your UK number stays active on your existing EE or Vodafone carrier while HelloRoam handles your travel data, all sorted before you leave home.
How do I transfer my eSIM to a new phone?+
Your HelloRoam eSIM cannot be moved to a new phone once installed. Scanning the original QR code again or using your phone's own transfer feature does not work for it. If it has not yet connected to a network your plan covers at your destination, email help@helloroam.com and HelloRoam can issue a new eSIM. After that first connection, its code cannot be used again. Do not delete the eSIM from your old phone. Some UK carriers support direct device-to-device transfer through their app.
How many eSIM profiles can I store on one phone?+
Many phones can store several eSIM profiles, with one or two active at a time, and the number depends on the model. You can keep travel eSIM plans for different countries stored on your device and switch on the right one when you travel. That is far more practical than carrying a wallet full of physical SIM cards from previous holidays.
