Can I switch from physical SIM to eSIM?+
Yes, switching to eSIM is straightforward with South African carriers. Open the Vodacom, MTN, or Telkom app and look for the eSIM option, or visit a service centre. You will get a QR code to scan, which loads your digital profile onto the phone. Your physical SIM deactivates once the transfer is done, so make sure everything is confirmed before you remove your old card.
Is eSIM better than a physical SIM card?+
For most travellers, yes. You skip the delivery queue and the airport kiosk, and your plan is ready before you board. In the eSIM vs physical SIM comparison, eSIM comes out ahead on convenience, cost and security: it installs over the air, with no card swap or store visit. HelloRoam eSIM plans start at R 16,79 and cover 185+ countries. Physical SIMs are still useful for older handsets without eSIM, or in destinations where local carrier eSIM support is thin.
Is eSIM more secure than physical SIM?+
eSIM beats physical SIM on security because nobody can pull the chip out and slot it into another handset. Your cellular connection is locked to your device until you deliberately initiate a transfer. A nano SIM card can be taken out of a lost or stolen phone and used in another one. SIM-swap fraud works differently: the scammer gets your carrier to move your number to a new SIM. The GSMA confirms that eSIM uses the same encryption standards that protect every cellular connection worldwide.
Should I get an eSIM or local SIM for the UK?+
A HelloRoam eSIM is the practical choice for a UK trip. Hunting for a local SIM after landing at Heathrow wastes your first hours in London. Activate your eSIM before you leave OR Tambo and you land already connected. Whether you are visiting family in the UK, on a working holiday, or a short-break tourist, skipping the SIM queue is worth it on its own.
What are the advantages of eSIM over physical SIM?+
eSIM advantages over physical SIM are clear: quick QR code activation, no plastic card to lose in your hand luggage, and the ability to hold several carrier profiles on one device. In an eSIM vs SIM card comparison, eSIM wins on convenience, security, and multi-country switching. HelloRoam eSIM connects you to 212+ networks across 185+ countries. Set up your plan before you fly and switch between destinations without visiting a single phone shop.
Is an eSIM safer or more private than a normal SIM card?+
Privacy-wise, eSIM and physical SIM are on equal footing. Both connect to cell towers through identical protocols, and the same network-level data handling applies to each. Where eSIM pulls ahead is physical security: no one can yank the chip from your phone and pocket it. HelloRoam eSIM profiles are tied to your device, use GSMA-standard encryption and cannot be pulled out like a physical card.
Can I have two eSIMs on one phone?+
Most current smartphones can hold two or more eSIM profiles. Apple iPhones from the XS (2018) onwards support dual SIM with a physical SIM and an eSIM, and the iPhone 13 range and newer can run two eSIMs at the same time without needing a physical SIM at all. Samsung Galaxy phones also keep two lines on at once: a physical SIM and an eSIM, or two eSIMs on select models. HelloRoam lets you layer a travel data plan on top of your existing Vodacom or MTN eSIM, so your South African number stays reachable while you are abroad.
Can your eSIM be hacked?+
An eSIM removes one common risk of a physical SIM. Because it is built into the phone, no one can pull it out and slot it into another device the way they can with a SIM card, so a thief cannot take it from a stolen phone and use it elsewhere. The GSMA encryption standard covers every HelloRoam eSIM profile across 185+ countries, which adds protection on every trip.
Do eSIMs give you a phone number?+
HelloRoam eSIM plans are data-only and do not issue a new phone number. Your South African number stays live on your primary SIM or carrier eSIM throughout your trip. That setup suits South African travellers well: your local number handles calls and WhatsApp while HelloRoam covers data across 185+ countries. Carrier eSIMs from Vodacom or MTN do come with a number tied to your account.
Do you keep your phone number with an eSIM?+
Your number is tied to your carrier account, not to the type of SIM card you use. Moving from a physical SIM to an eSIM with the same carrier leaves your number completely unchanged. Adding a HelloRoam travel eSIM on top does not affect your South African number at all. Your home line stays live for calls and texts while HelloRoam handles data in 185+ countries.
