eSIM Not Working in India? Common Problems and Quick Fixes
Practical troubleshooting for NRIs from the USA, Canada, UK, and Australia whose eSIM isn't connecting, activating, or working as expected during their India trip.
If your eSIM not working India travel is a problem you're facing right now, you're not alone — it can be stressful, especially right after you've landed and just want to message family or pull up directions. The good news is that most eSIM issues come down to a small number of common causes, and almost all of them can be fixed in a few minutes without needing a store visit or a new SIM.
Before you troubleshoot: Make sure your phone is unlocked and eSIM-compatible, and that you installed the eSIM profile using a stable Wi-Fi connection — most activation problems trace back to one of these two things.
eSIM Not Working India Travel: "No Service" or No Signal
What's happening
The eSIM is installed, but your phone isn't picking up a network connection in India.
Fix
Go to your phone's network settings and confirm the eSIM line is set as the active data line, not your home SIM. Toggle Airplane Mode on and off to force a network reconnect. If that doesn't work, manually select the network operator instead of leaving it on automatic — this often resolves connection issues right after landing.
Problem 2: QR Code Won't Scan or Activation Fails
What's happening
You're trying to install the eSIM profile, but the QR code scan fails or gets stuck.
Fix
Make sure you're connected to Wi-Fi before scanning — eSIM installation needs an active internet connection to complete. If the camera scan keeps failing, most providers also offer a manual entry option (SM-DP+ address and activation code) in your confirmation email, which you can enter directly in your phone's eSIM settings instead of scanning.
Problem 3: eSIM Installed but Data Isn't Working
What's happening
The eSIM shows as installed and active, but you still can't browse or load anything.
Fix
Check that mobile data is turned on for the eSIM line specifically (phones with dual SIM support let you choose which line handles data). Also confirm data roaming is enabled for that eSIM line — many phones disable this by default, even for eSIMs meant to work locally in India.
Problem 4: Can't Use Hotspot or Tethering
What's happening
Your eSIM data works on the phone itself, but sharing it via hotspot to a laptop or another device doesn't.
Fix
Not all eSIM data plans include hotspot/tethering by default — check your specific plan's terms. If hotspot is included, make sure it's enabled in your phone's settings under the eSIM's data line, since hotspot permissions are sometimes tied to a specific SIM slot.
Problem 5: Data Is Very Slow
What's happening
You have a connection, but speeds are much slower than expected.
Fix
Slow speeds are often a network coverage issue in a specific area rather than a plan problem — this is more common in rural regions or smaller towns. Try switching between 4G/5G network mode manually in settings, and if you're indoors, move closer to a window, since building materials can weaken signal strength.
Problem 6: eSIM Suddenly Stops Working Mid-Trip
What's happening
Everything was working fine, but the eSIM has now disconnected or shows an error.
Fix
Check your remaining data balance first — many eSIM plans simply stop working once the data allowance runs out, rather than showing a clear warning. If you still have data left, restart your phone, as this resolves most temporary network glitches.

If you've tried the fixes above and your eSIM still isn't working, it's worth reaching out to your provider's support directly — most eSIM companies offer in-app or email support and can check whether the issue is on their end, such as a network outage in your specific area or a problem with your plan's activation. You can also check real-time network status using a tool like Downdetector to rule out a wider outage.
Frequently Asked Questions
Why is my eSIM not working when I land in India?
The most common reason is that the eSIM line isn't set as the active data line, or data roaming isn't enabled for it. Checking these two settings resolves the issue in most cases.
Can I fix eSIM activation problems without Wi-Fi?
Not usually — eSIM installation requires an active internet connection to download the profile, so you'll need Wi-Fi if your phone has no other data connection at the time.
Why does my eSIM work for calls but not data?
This typically means data roaming is disabled for that specific line, or mobile data is set to route through your other SIM instead of the eSIM.
Does restarting my phone help fix eSIM issues?
Yes, a restart resolves many temporary network glitches and is worth trying before reaching out to your provider's support team.
