Can I switch from physical SIM to eSIM?+
Switching from physical SIM to eSIM is straightforward with Three Ireland, Vodafone IE, and Eir. Open your carrier app and look for the eSIM option, or contact support directly. You will receive a QR code to scan, which installs your digital profile in minutes. Your physical SIM stops working once the eSIM activates, so confirm the transfer is complete before removing your old card.
Is eSIM better than a physical SIM card?+
Is eSIM better than a physical SIM card? Yes, for most travellers. It installs over the air with a QR code scan, so there's no card swap, no shop visit and no nano SIM card to lose. The eSIM vs physical SIM comparison shows eSIM wins on ease of setup, cost, and security for most trips. HelloRoam eSIM plans start at €0.89 and cover 185+ countries. Physical SIMs still make sense for phones without eSIM, such as many budget models (check your phone's settings), or destinations with limited eSIM carrier coverage.
Is eSIM more secure than physical SIM?+
An eSIM has one clear security edge over a physical SIM: it's built into your phone, so no one can pull it out and put it into another phone. Your HelloRoam connection stays tied to the phone you install it on. A physical SIM can be taken out of a lost or stolen phone and used in another one. SIM-swap fraud is different: it happens at the carrier, when someone gets your number moved to a new SIM. HelloRoam eSIM profiles follow the GSMA encryption standard for all plans across 185+ countries.
Should I get an eSIM or local SIM for India?+
eSIM works well for travel to India, and major carriers including Airtel and Vi support it. A local physical SIM in India can cost less per GB, but it requires an in-person visit, a passport copy, and sometimes a wait for activation. An eSIM activates before you land and skips all of that. For a short holiday, the convenience of eSIM easily outweighs the slight price difference.
What are the advantages of eSIM over physical SIM?+
eSIM advantages over a physical SIM include instant activation via QR code, no plastic card to lose, and the ability to store multiple carrier profiles on one device. In an esim card vs sim card comparison, eSIM wins on convenience, security, and multi-country switching. HelloRoam eSIM connects you to 212+ networks across 185+ countries. You can activate a travel plan before your flight and switch between countries without setting foot in a phone shop.
Can I be tracked with an eSIM?+
Tracking works the same way whether you use an eSIM or a physical SIM. Both connect to cell towers using identical cellular protocols. Your carrier and local networks can approximate your location through tower data regardless of SIM type. The GSMA confirms eSIM meets identical security standards to physical SIM cards. HelloRoam eSIM profiles are device-locked with encryption and cannot be physically removed.
Can I have two eSIMs on one phone?+
Most modern smartphones can store more than one eSIM profile. iPhone XS and newer models with a SIM tray run one physical SIM and one eSIM at the same time. The iPhone 13 and later can run two eSIMs at the same time without a physical SIM. Google Pixel 7 and later can also run two eSIMs if your carrier allows it. HelloRoam lets you add a travel data plan alongside your home carrier eSIM so your Irish number stays reachable while you use affordable local data abroad.
Can your eSIM be hacked?+
An eSIM is built into your phone, so no one can pull it out and put it into another phone the way they can with a physical SIM card. The GSMA encryption standard protects all HelloRoam eSIM profiles across 185+ countries. SIM-swap fraud happens at the carrier, when someone gets your number moved to a new SIM, so it can affect any line, eSIM or physical.
Do eSIMs give you a phone number?+
HelloRoam eSIM plans provide data-only connectivity and do not assign a new phone number. Your existing Irish number stays active on your primary SIM or carrier eSIM. This setup works well for travellers: your home number handles calls and texts while HelloRoam covers data across 185+ countries. Carrier eSIMs from Three Ireland or Vodafone IE do come with a phone number tied to your account.
Do you keep your phone number with an eSIM?+
Your phone number stays with your carrier, not your SIM type. Switching from a physical SIM to an eSIM with the same carrier keeps your number exactly as it was. Adding a HelloRoam travel eSIM does not touch your existing number at all. Your home line stays active for calls and texts while the HelloRoam eSIM handles data in 185+ countries.
