Everything you need to know about eSIM technology: how it works, compatible phones, installation, and why it's the best choice for travel.
DIRECT ANSWER
An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of inserting a physical plastic card, you install a software profile by scanning a QR code. This gives you instant access to local mobile networks abroad without roaming fees, airport queues, or swapping SIMs. eSIM works on iPhone XS+, Google Pixel 3+, Samsung Galaxy S20+, and most recent smartphones.
An eSIM works exactly like a traditional SIM card but without the physical plastic. Your phone has a small, rewritable chip soldered to the motherboard. When you purchase a TravelNet eSIM plan, your phone downloads a secure profile over WiFi that contains your data plan information. This profile authenticates your device with local partner networks when you travel, granting you access to 4G/5G data without needing a separate physical card for each country.
Choose your destination and data plan on the TravelNet website. Complete checkout with Visa, PayPal, or Apple Pay.
Within 2 minutes of purchase, you receive a QR code and installation instructions by email. No physical card to wait for.
On iPhone: Settings > Cellular > Add Cellular Plan, then scan the QR code. On Android: Settings > Connections > SIM Manager > Add eSIM.
Enable mobile data and data roaming for the eSIM line. Your phone connects automatically to the local partner network.
eSIM technology has transformed international travel connectivity. Travelers no longer need to hunt for local SIM shops, pay exorbitant roaming fees, or carry multiple phones.

An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of inserting a physical plastic card, you install a software profile by scanning a QR code. This profile connects your phone to local mobile networks when you travel, giving you data access without roaming fees. Unlike a physical SIM, an eSIM cannot be lost, damaged, or stolen, and you can store multiple profiles on one device.
Functionally, yes — both connect your phone to a mobile network. The difference is physical: a regular SIM is a removable plastic card, while an eSIM is a digital profile embedded in your phone's hardware. eSIMs offer more flexibility: you can switch plans without waiting for a physical card, use your home SIM for calls while the eSIM handles data, and pre-load multiple travel profiles.
eSIM is supported on most modern smartphones: iPhone XS and newer (including all iPhone 12-16 models), Google Pixel 3 and newer, Samsung Galaxy S20 and newer (including Z Fold and Z Flip series), and recent models from Huawei, Oppo, OnePlus, and Motorola. To check your phone, dial *#06# — if an EID number appears, your device is eSIM-compatible.
After purchasing a TravelNet eSIM, scan the QR code sent to your email. On iPhone: Settings > Cellular > Add Cellular Plan. On Android: Settings > Connections > SIM Manager > Add eSIM. Installation takes under 2 minutes and should be done before departure on WiFi. The profile activates automatically when you arrive at your destination and enable data roaming.
Yes, this is one of the biggest advantages of eSIM. Most modern phones support Dual SIM mode, letting you keep your physical SIM active for calls and SMS on your home number while the eSIM provides data connectivity abroad. Both work simultaneously, so you never miss important calls.
Yes, eSIM is very secure. The profile is encrypted and tied to your specific device. Unlike a physical SIM, it cannot be removed or swapped if your phone is lost or stolen. eSIMs also eliminate the risk of SIM swap fraud since the profile cannot be transferred without authorization from your provider.
Yes, regional and global eSIM plans cover multiple countries with a single profile. TravelNet offers Europe eSIM (40+ countries), Asia eSIM (30+ countries), and Worldwide eSIM (190+ countries). The connection switches automatically as you cross borders, with no need to install a new profile or pay extra fees.
TravelNet eSIM plans start at $1.04 for short trips. A typical week-long plan costs $4.90 to $14.90 depending on data allowance. Unlimited data plans start at $24.90 for a month. This is 80-97% cheaper than traditional international roaming and often cheaper than local tourist SIM cards.
