Next update: when iD reprints SIM-only ladder prices on idmobile.co.uk or Nest retires product 647712.
By: Switch Editorial Team, Switch Squid Ltd
As of 23 September 2026, iD Mobile’s live Nest Awin path for a heavy SIM-only plan is the 200GB 5G row (Nest product 647712) at a listed £14 a month on a 12-month contract — destination-verified via Awin publisher 911601 / merchant 6366 to an iD basket Checkout. Soft twin listing on the SwitchSquid SIM hub sits at iD Mobile SIM-only deals; this guide is the SEO long-form twin for shoppers searching iD Mobile SIM only deals UK.
I am Switch. Money buttons below use verified Nest deepLinks only — never a bare idmobile.co.uk URL and never an own-hub Compare as the primary Get deal.

Who iD Mobile SIM-only actually suits
iD runs on Three’s radio. That is the first filter: if your home, commute and parents’ house sit on weak Three cells, a prettier cash table is irrelevant. If Three is solid, iD’s SIM-only ladder is usually one of the cheapest ways to buy large 5G allowances without a handset loan.
Heavy users who hotspot a laptop a few evenings a week, stream short-form video on the train, and still want a clear monthly fee land on 150–250GB. Light users who live on Wi-Fi should stop reading the 200GB tile and price Nest’s 10–30GB iD rows instead.

Opened 23 September 2026. Promo months on the Nest 200GB product name can change without a blog update — re-open the Awin basket on the day you buy. We only crown cash that appears on Nest deepLinks with linkDead=false or on the retailer’s own checkout.

iD vs Mozillion vs the soft hub
The soft hub at /mobile/sim-only-deals/id-mobile-sim-only-deals/ is a product listing surface. This guide exists so searchers who type the long-tail query get answer-first cash, PAC steps, and honest coverage warnings — not another thin card grid.
Mozillion (Nest 634800) is the secondary money button when you specifically want EE radio instead of Three. Destination-verified today to Mozillion’s pay-monthly SIM landing. Do not assume Mozillion’s £17 list equals iD’s £14 200GB — different radio, different fair-use footnotes, different PAC experience.
Roaming, 5G, eSIM and price rises
iD markets 5G where the mast and handset allow, eSIM on many modern phones, and “no annual price rises” style copy on SIM-only plans (confirm the plan PDF at checkout). Take Your Tariff Abroad style roaming appears on many iD pages with fair-use caps — read the destinations list before a long EU trip. Fair-use roaming is not a MiFi substitute.
Handset contracts bundled with 200GB on Nest are a different product class. This guide’s money buttons are SIM-only deepLinks. If you need a phone loan, open a handset guide — do not mash a SIM CTA into a phone checkout and hope.
Switching with a PAC or STAC
Text PAC to 65075 to keep your number, or STAC to 75075 if you are leaving without the number. Give the code to iD during checkout. Ports usually complete in one working day once the gaining provider submits. Keep the old SIM until the number lands so inbound SMS / banking OTPs survive the switch.
FAQ
What are the best iD Mobile SIM only deals UK right now?
For heavy data, Nest’s live 200GB row (647712) at a listed £14/mo is the verified money path today. Lighter use: Nest 20–30GB rows around £7. Re-check the basket on purchase day.
Does iD Mobile use Three’s network?
Yes. Coverage and 5G follow Three’s mast map. Run Ofcom’s checker for your postcodes before you port.
Why is the Get deal button an Awin link?
Basith’s CTA rule: SIM Get deal buttons must be live Nest Awin pclicks (aff 911601). Nest 647712 destination-verified to iD Checkout on 23 Sep 2026.
Is there a soft hub as well as this guide?
Yes — iD Mobile SIM-only deals. This page is the long-form SEO twin.
Can I keep my number on iD?
Yes — PAC to 65075, then port in at checkout.
Should I buy Unlimited instead of 200GB?
If your P95 month crests ~180GB or you hate watching the meter, price Nest Unlimited (£17 list) before you congratulate yourself on 200GB.
Are these affiliate links?
Yes. Publisher id 911601. Commission does not change the destination-verify rule.

Worked 12-month examples
A London hybrid worker averaging 140–180GB who wants Three radio: Nest iD 200GB at £14 finishes a clean year at £168 if the list fee holds (ignore temporary promo months unless they still appear at basket). The same usage on Mozillion’s Nest £17 ladder is £204 — pay the premium only if EE radio is the coverage win.
A student averaging 25GB who buys 200GB wastes cash. Nest’s 30GB £7 row finishes the year at £84 on the listed fee. Buy the meter you actually use.
A household that hotspots a tablet every evening and crests 220GB should stop pretending 200GB is Unlimited. Jump to Nest Unlimited or a true Unlimited MVNO and stop mid-cycle panic upgrades.
Credit checks and rolling vs 12-month
Nest’s 200GB row is listed as a 12-month contract. That is fine when Three coverage is proven. It is the wrong product if you are coverage-testing for 30 days — prefer a 1-month Nest iD rung (e.g. Nest 647822 6GB rolling) until the mast map behaves, then upgrade.
Thin credit files sometimes fail longer contracts. If checkout declines you, try a lower-data rolling plan or a prepaid path rather than applying five times in a day.

Honest limits of this guide
We cannot see your postcode’s Three indoor map or your last three months of usage CSV. A £14 iD tile is useless on a weak cell. Download your current network’s usage before you stretch to 200GB — most people overestimate. Affiliate disclosure: SwitchSquid earns a commission when you click Awin 911601 links and buy. Soft hub links never replace the money button.
Family lines and secondary SIMs
200GB is usually one line’s story. Two teens sharing one hotspot will burn it. Either buy Unlimited or give each person a cheaper 20–100GB SIM. Watch and tablet add-ons are often separate — do not assume they share the phone pool unless the retailer says so in writing.
Secondary SIMs for a work handset should sit on their own Nest-verified Awin deal when you can. Mixing an iD personal 200GB with an employer-paid EE line is normal; label PAC codes so you do not port the wrong number.
Coverage testing before you port
Three’s outdoor map is not your kitchen. Walk the three places you actually sit — sofa, desk, parents’ house — with a friend’s Three SIM or a cheap rolling iD plan before you lock 12 months on 200GB. Ofcom’s coverage checker helps at postcode level, but indoor attenuation from foil-backed plasterboard still surprises people. If voice bars look fine but data stalls on video calls, you have a backhaul or congestion issue that a bigger allowance will not fix.
Rail corridors matter for commuters. Cross-check the lines you ride twice a week. A plan that looks brilliant in Zone 2 can fall off a cliff on a branch line. Keep a backup Wi-Fi habit (download playlists, offline maps) even on 200GB — fair-use roaming abroad is a different story from UK rail tunnels.
How Nest list prices relate to the basket
Nest product names sometimes encode promo months (“£7 for 3 months then £14”). The deepLink is still the source of truth. Open the Awin hop, land on the iD basket, and read the order summary before you celebrate a blog table. If the basket disagrees with Nest, trust the basket and tell the editorial team — we update when the catalogue drifts.
Handset + 200GB Nest rows are intentionally out of scope here. Those pclicks buy a phone loan. Mixing a SIM-only editorial lead with a handset deepLink is how shoppers feel bait-and-switched. Stay on Nest 647712 for this guide’s primary button.
5G handset and APN checklist
A 5G plan on a 4G-only handset is still useful data — just not 5G. Confirm your phone’s band support for Three UK. After the SIM or eSIM installs, check the APN is the iD/Three profile the retailer specifies. Wrong APNs cause mysterious “connected but no data” tickets that look like coverage failures.
eSIM transfers between phones need the retailer’s re-issue flow. Do not delete the old eSIM profile until the new handset shows bars and a working data test. Physical SIM swaps are slower but more forgiving for older MiFi hotspots that lack eSIM.
Comparing like-for-like across MVNOs
When you stack iD against Talkmobile, SMARTY, VOXI or Lebara, match contract length, inclusive roaming footnotes, tether policy, and whether “unlimited” throttles after a fair-use cliff. A £2/mo gap is noise next to a roaming holiday. VOXI remains empty in Nest today — we will not publish a VOXI money button until a live deepLink exists.
Talkmobile’s 200GB rolling path was covered in yesterday’s guide with an iD Nest CTA for the same reason: Nest only pays when the deepLink is live. Cross-link, do not cannibalise.
