A SIM card built into your phone.
A digital SIM that lives inside your phone. Instead of swapping a physical card, you scan a QR code to activate a local data plan — no roaming fees, no airport SIM hunt.
No physical SIM
Your eSIM downloads straight to your phone — nothing to mail, nothing to swap.
Activated in seconds
Scan a QR code and you're online. The whole setup takes about 30 seconds.
Works in 190+ countries
One provider, dozens of local networks. Land connected wherever you go.
Keep your main number
Your eSIM runs as a secondary line — calls and iMessage stay on your home SIM.

Sound familiar?
You land. Your phone latches onto a foreign carrier. Your bill quietly starts to explode — and you don't find out until weeks later.
Roaming, $15/day
Carriers turn it on the moment you land — billed silently, often for plans you never picked.
Airport WiFi, 30-min limit
Just long enough to find your bag. Not long enough to book a ride or text your family.
Group chats go dark
iMessage and WhatsApp stop syncing. The first hours abroad are the loneliest.
Surprise charges, weeks later
A $47 data charge here, a $200 bill there. The damage shows up after you're home.

The latest advice on staying connected wherever you're headed.
KnowRoaming vs Lotsotravel: The Sticker Pioneer Went eSIM-Only (2026)
KnowRoaming invented the roaming SIM sticker in 2013. It doesn't sell one any more. We priced its current eSIM plans against Lotsotravel across the USA, Europe and Japan: the Europe gap is wide, the single-country gap is narrow.
Read moreThe True Cost of O2 UK's Free Europe Zone Roaming (2026) vs. Lotsotravel eSIM
O2 is the only major UK network that never brought back EU roaming charges. But the free allowance caps at 25GB a month, past which you buy Data Bolt Ons at £2.70-£12.50 per GB, and long stays run into a 63-day fair-use rule. We price real itineraries against a Lotsotravel Europe+ eSIM to show exactly when O2 is enough and when it isn't.
Read moreThe True Cost of Singtel DataRoam in Europe (2026) vs. Lotsotravel eSIM
Singtel's DataRoam Unlimited Daily costs $29 SGD/day in Europe, not the $19 headline rate, and it only covers one country per subscription. Skip it and you're exposed to $25 SGD/MB pay-per-use. We price real European itineraries to show why a Lotsotravel eSIM saves Singapore travelers 92-95% on every multi-day trip.
