Partnered with leading network operators
traverrsim runs on tier-1 carriers in every destination we sell. Activate your eSIM and it connects to the best local network automatically.
How it works
1. Install before you fly
Scan the QR code at home. The eSIM sits quietly on your phone until you travel.
2. Land and switch on
Turn off airplane mode. No app, no counter queue, no local SIM swap.
3. Auto-connect to a top local network
Your eSIM registers on our partner carrier in that country — the same network locals use.
4. Online in seconds
Maps, WhatsApp and rides work straight away, at full local 4G/5G speed.
Why not the cheapest network?
Some eSIM brands buy the lowest-ranked network in a country because it costs them the least. You only notice on day one — no signal on the train, dead zones in the mall, nothing outside the city. We pay for the top-ranked operators instead. You get what you pay for.

FAQ
Which network will I connect to?
The top local carrier in that country — like NTT DoCoMo in Japan, SK Telecom in Korea, or Singtel in Singapore. Your phone picks it automatically.
Do I need to choose the network myself?
No. It connects on its own. If you ever lose signal, you can pick the carrier manually in your phone settings.
Why are some other eSIMs cheaper?
Cheap eSIMs usually ride on the smallest carrier in the country. It looks fine on paper, then drops out on trains, in malls and outside the city. We pay more for tier-1 networks so your data actually works.
Will I get 5G?
Yes, where the local partner has 5G and your phone supports it. Otherwise you get full-speed 4G/LTE.
Is the speed throttled?
No hidden throttle on our Total plans. You get the same speed as a local customer on that network.
