Calling India from the UK costs around £0.50–£1.00 per minute on a standard O2 or EE tariff — unless you buy an add-on. Add-ons cut that cost, but they're not always the cheapest option once you do the maths. This article compares O2's and EE's India calling add-ons against browser-based VoIP at real per-minute rates, so you can see exactly what you'd pay for 60, 120, or 300 minutes a month.
Key Takeaways:
- EE's International Calling add-on charges around £0.25/min to India; O2's comparable add-on sits near £0.25–£0.30/min — both far above VoIP rates of £0.06/min (≈$0.08).
- For 300 minutes/month to India, carrier add-ons cost £75–£90; VoIP costs roughly £18–£24.
- Browser-based VoIP requires no app, no SIM, and no monthly commitment — you pay only for what you use.

What O2 Actually Charges for Calls to India
O2's standard out-of-bundle rate to India is around £1.00/min. With their International Bolt-On (roughly £5/month), that drops — but not to a rate you'd call cheap. Calls to Indian mobiles on the bolt-on land somewhere around £0.25–£0.30/min depending on your plan tier.
That £5/month sounds harmless. But it's a fixed fee you pay even in months you barely call. Make 10 minutes of calls to India in a quiet month and you've just paid an effective rate of £0.50/min on top of the bolt-on fee. The maths only works in your favour if you're consistently racking up call time every single month.
O2 also restricts which numbers qualify. Indian mobile numbers (starting +91 98xx, 99xx, etc.) may be rated differently from landlines. Always check the fine print before assuming the add-on covers what you need.
What EE Charges — and Where It Catches You Out
EE's International Calling Extra add-on is similarly priced in the £4–£7/month range, with per-minute rates to India typically around £0.25/min for mobiles. Some EE plans include a small bundle of international minutes, but India often isn't in the "standard" bundle countries — it falls into a separate tier.
Here's what most people miss: EE charges connection fees on some calls. A 3p or 5p connection fee per call sounds trivial. Make 20 short calls in a month and that's an extra £0.60–£1.00 before you've spoken a word. If you're making lots of short check-in calls to family in Mumbai or Chennai, those pennies add up fast.
EE also automatically renews add-ons monthly. Forget to cancel after a quieter month and you've paid again for nothing.
The Real Cost at 60, 120, and 300 Minutes Per Month
Hard numbers make this easier. For calls to India specifically, here's what each option costs at different call volumes. GlobCall rates India at $0.08/min (roughly £0.06/min at current rates).
At 60 minutes/month:
- O2 add-on (£5 fee + £0.28/min): £5 + £16.80 = £21.80
- EE add-on (£5 fee + £0.25/min): £5 + £15.00 = £20.00
- VoIP at £0.06/min: £3.60
At 120 minutes/month:
- O2: £5 + £33.60 = £38.60
- EE: £5 + £30.00 = £35.00
- VoIP: £7.20
At 300 minutes/month:
- O2: £5 + £84.00 = £89.00
- EE: £5 + £75.00 = £80.00
- VoIP: £18.00
At 300 minutes, VoIP is roughly 4–5× cheaper. That's not a marginal difference. That's the kind of saving that pays for a flight.
If you want to go deeper on what drives these per-minute differences, this breakdown of how VoIP international call rates work is worth a read.
Why VoIP Beats Add-Ons for Regular Callers to India
VoIP routes calls over the internet rather than through the mobile network. No carrier markup. No bolt-on fee. No connection charge. You pay the wholesale termination rate and that's it.
For India specifically, VoIP rates from reputable providers sit around $0.08/min (£0.06/min). Compare that to £0.25–£0.30/min on O2 or EE, and you're looking at a 4× cost difference for every single minute. The savings compound fast.
Browser-based VoIP is particularly useful here because you don't need to install anything. Open a tab, add credit, dial. Works on any device with a decent internet connection — no new SIM, no app update breaking things at 11pm when you're trying to reach family. For a full walkthrough of how this works in practice, see how to make cheap international calls directly in your browser.
The only scenario where a carrier add-on makes sense is if you make very occasional, short calls and already have the add-on bundled with your plan at no extra cost. For anyone calling India regularly — weekly family calls, remote work with Indian colleagues, managing a business relationship — VoIP wins every time.
Does Call Quality Differ?
With a good broadband or Wi-Fi connection, VoIP quality to India is indistinguishable from a carrier call. Often better, because you're not routing through an overloaded international mobile gateway.
The longer answer involves a few variables. Jitter and packet loss on your internet connection will affect VoIP quality — if your broadband is patchy, you might notice it. Indian network infrastructure also varies by region: calling a landline in Delhi is a different experience from calling a mobile in a rural area.
For business calls where clarity matters, a wired connection beats Wi-Fi every time. A £5 ethernet adapter for your laptop solves 90% of the quality issues people blame on VoIP.

What About Roaming? (If You're Travelling)
Carrier add-ons get considerably more expensive once you leave the UK. O2 and EE add-ons apply to calls made from UK numbers on UK networks. Use your phone abroad and roaming rates kick in on top.
VoIP doesn't care where you are. Log in from your hotel in Bangkok, your flat in Manchester, or a café in Lisbon. The rate to call India stays the same: $0.08/min. No roaming surcharge. No "you must be in the UK to use this feature" restriction.
This is particularly relevant for Indian expats in the UK who travel back to India regularly. While you're visiting family, you might want to call UK numbers — or call other Indian numbers from within India cheaply. VoIP handles both directions without any plan changes. For more on that, this guide on calling India from the UK cheaply covers the full picture.
Frequently Asked Questions
Is there a free trial for VoIP calls to India?
GlobCall offers 60 free minutes for new users — enough to make a solid test call to India and judge quality for yourself before adding any credit. You can claim that here. It's a proper call, not a demo.
Do O2 and EE add-ons cover Indian landlines and mobiles the same?
Not always. Many carrier add-ons rate Indian mobiles and landlines separately, with mobiles often costing more. Check your specific plan's rate card — the advertised add-on rate sometimes applies only to landlines. VoIP providers typically publish one rate for India mobile numbers and a separate (often lower) rate for landlines.
Can I use VoIP from my mobile phone?
Yes. Browser-based VoIP works in any modern mobile browser — Chrome, Safari, Firefox. No app download needed. Your phone just needs a working Wi-Fi or data connection. If you're on mobile data, 4G or better works fine for voice calls.
What if I need to call India very occasionally?
If you're making one or two calls per year, a carrier add-on's monthly fee is pure waste. Pay-as-you-go VoIP at $0.08/min means a 10-minute call costs £0.60. No monthly fee, no commitment. You add credit when you need it, use what you use, and nothing expires on a billing cycle.
Is it legal to use VoIP for international calls in the UK?
Completely legal. VoIP is a standard, regulated communications technology used by millions of UK residents and businesses. There's no restriction on using internet-based calling services for international calls.
The numbers don't lie. Here's what you're actually looking at:
- O2 and EE add-ons cost £0.25–£0.30/min to India, plus a monthly bolt-on fee of £4–£7 whether you use it or not
- VoIP rates to India run around £0.06/min with no monthly fee and no connection charges
- At 300 minutes/month, carrier add-ons cost £80–£90; VoIP costs around £18
- Quality is comparable on a decent connection — often better through VoIP on a wired or strong Wi-Fi connection
- Roaming changes everything for carrier add-ons; VoIP rate stays flat wherever you are
If you're calling India more than once a week, a carrier add-on is costing you real money for no good reason. Try it yourself — make a call to India right now and see what £0.06/min actually sounds like.
