- Re-enable Indian plan or set physical SIM as default data
- Travel eSIM stored — reactivate for next trip
Common eSIM Problems on S25 Ultra and Fixes
Only one EID showing despite S25 Ultra
Fix: Your variant may not support dual eSIM despite being an S25 Ultra model number. China variants and some specific market variants have eSIM disabled. Confirm via *#06# — two EIDs = dual eSIM confirmed.
“Add eSIM” not appearing in SIM Manager
Fix 1: Update One UI 7 — Settings → Software Update.
Fix 2: Restart phone — One UI 7 occasionally needs a restart after software updates for eSIM features to appear.
Fix 3: Phone may be carrier-locked — contact Samsung support or the original carrier.
QR code scan failing on S25 Ultra
Fix: Clean the S25 Ultra camera lens (titanium frame edge near camera). Increase brightness on the QR code display device. Use manual activation code entry as an alternative.
eSIM Slot 2 showing “No Service” after activation
Fix: Toggle Airplane Mode on and off to force network re-registration for both slots. Settings → Connections → Mobile Networks → Network operators → Search manually → select carrier for Slot 2 specifically.
Data not switching between eSIMs
Fix: Settings → Connections → SIM Manager → Mobile Data → tap to switch active data SIM. S25 Ultra data switching takes 5–15 seconds — wait for completion before testing.
Third SIM (eSIM Slot 2) causing battery drain
Fix: Running three active SIM slots increases radio activity. This is normal — Snapdragon 8 Elite handles it efficiently, but triple SIM does use more battery than a single SIM. Set eSIM Slot 2 to data-only if voice is not needed on that line — reduces radio scanning.

Key progression: Dual eSIM arrived with S24 Ultra and continues with S25 Ultra — giving Indian power users genuine triple SIM capability for the first time in Samsung’s mainstream lineup.
eSIM Transfer — Moving to S25 Ultra from Previous Phone
From S24 Ultra (dual eSIM to dual eSIM)
- Note both S25 Ultra EIDs from *#06#
- Contact each carrier separately — provide the respective S25 Ultra EID
- Carrier deactivates S24 Ultra eSIM → generates a new QR code for the S25 Ultra EID
- Scan on S25 Ultra → assign to correct slot
From S23 Ultra (single eSIM to dual eSIM)
Same process — you now have an additional eSIM slot available. Can activate a second carrier on Slot 2, which was not possible on the S23 Ultra.
From iPhone to S25 Ultra
Contact carrier with S25 Ultra EID (specify which slot) — carrier re-issues eSIM for new device. Standard 10–15 minute process.
Frequently Asked Questions
Can S25 Ultra run 3 SIMs simultaneously?
Yes — one physical nano-SIM and two eSIMs simultaneously. All three receive calls and SMS. Only one SIM handles mobile data at a time — switch from Quick Settings.
Can I use two Jio numbers on S25 Ultra?
Yes — one Jio number on a physical SIM and another on eSIM Slot 1, with a third carrier on eSIM Slot 2. Or two Jio eSIM profiles on Slot 1 and Slot 2, with a physical SIM for the third carrier. Contact Jio separately for each eSIM activation with the respective EID.
What happens to dual eSIM if I factory reset S25 Ultra?
A factory reset deletes all eSIM profiles from both slots permanently. Before resetting: Settings → General Management → Reset → Erase All Content → iOS prompts you to keep or delete the eSIM. On Samsung, back up eSIM details with each carrier before resetting. Provide EIDs post-reset for re-issuance.
Does S25 Ultra support 5G on all three SIMs?
The S25 Ultra supports 5G — but only the active data SIM uses 5G data. All three SIMs can receive voice calls on their respective network bands simultaneously. Jio and Airtel 5G both work on the S25 Ultra’s physical SIM and eSIM slots.
Is Galaxy S25 Ultra eSIM compatible with international travel eSIMs?
Yes. Airalo, Nomad, Holafly, and other international eSIM providers work on both S25 Ultra eSIM slots. Download a travel eSIM to Slot 2 while keeping the Indian eSIM active on Slot 1 and the Indian physical SIM for OTPs and banking.
Does S25 Ultra eSIM work with Samsung Knox Enterprise?
Yes — Knox Enterprise MDM can manage both eSIM slots remotely. Enterprise IT can provision, activate, and delete eSIM profiles on both slots without physical device access — useful for corporate device management.
Conclusion
The Samsung Galaxy S25 Ultra represents the most capable eSIM implementation Samsung has ever shipped — dual eSIM plus physical SIM gives Indian power users genuine triple connectivity that was impossible on previous Ultra models.
The practical impact is immediate for Indian users: personal number on physical SIM, work number on eSIM Slot 1, and international travel plan on eSIM Slot 2 — all active simultaneously, all manageable from One UI 7’s redesigned SIM Manager.
Setting up is straightforward — dial *#06# to confirm both EIDs, update to One UI 7, connect to Wi-Fi, and activate through your carrier’s app or QR code. The entire triple SIM setup takes under 20 minutes.
For Indian business executives and frequent travelers specifically, the S25 Ultra’s dual eSIM capability is not just a feature — it fundamentally changes how you manage connectivity across personal, professional, and international contexts on a single device.
