Every year, millions of Indian travelers pay ₹2,000–₹8,000 for international roaming packs from Jio, Airtel, or Vi — not realizing they could get the same or better connectivity for ₹600–₹2,000 with a travel eSIM.
This post breaks down exactly how much you overpay with Indian carrier roaming, destination by destination.
How Jio/Airtel international roaming works
When you activate an international roaming pack, your Indian carrier (Jio, Airtel) is buying wholesale data access from a local partner carrier at your destination — and charging you a significant markup.
You're connected to whichever carrier Jio/Airtel has a roaming agreement with. This is often NOT the best local network. In Japan, Jio's roaming partner might be KDDI while the best network is Docomo. You get the secondary option at a premium price.
A travel eSIM connects you to the best local network directly — no middleman, no markup.

That's a nice dinner in Paris or two nights in a better hotel in Kyoto.
The quality argument: eSIM wins there too
It's not just about price. Indian carrier roaming has a well-known quality problem:
- Connected to secondary partner networks, not the best local carrier
- Customer support requires calling India (expensive, time-zone friction)
- Data speeds capped by roaming agreement terms
- Packet prioritisation: roaming data deprioritised vs local customers during congestion
Trovio's eSIM connects directly to the primary network at destination — same network, same speed, same prioritisation as a local prepaid customer.
When does carrier roaming make sense?
Carrier roaming is worth considering if:
- Your phone doesn't support eSIM
- You're going to an obscure destination not covered by eSIM providers
- Your company reimburses roaming but not third-party eSIMs (check your policy — most accept receipts)
- You genuinely prefer a single bill from your existing carrier
For everyone else — especially Indian travelers with a Dual SIM + eSIM compatible phone — the eSIM saves thousands of rupees per trip.
