giffgaff Banned in China? Keep Your UK Number (PAC) and Pick Safer Alternatives (2026)

In late summer 2026, a cluster of prepaid giffgaff users said their UK numbers were disconnected after long stretches of roaming — especially from mainland China. Community threads and UK tech coverage treated it as a risk-control sweep, not a country-wide “China ban.” Official notices, where people received them, pointed back to giffgaff’s terms: the service is meant for primary use in the UK, with roaming for short-term travel.

If your giffgaff line still works, or you just received a disconnection email, the useful question is not “how do I keep roaming on a UK PAYG SIM from China forever.” It is: do you need this exact +44 number, or do you mainly need data and a way to receive codes?

This page is a dated snapshot (8 September 2026). Policies, help-centre steps, and roaming lists change. Verify anything that affects your number on giffgaff’s official help pages and the notice you were sent — not on a forum screenshot.

What we know, and what we do not

What independent coverage has reported. In early August 2026, ISPreview published customer emails and a giffgaff spokesperson comment: the company said it had identified PAYG SIMs tied to “extended or permanent use outside the UK,” called that a breach of its terms, and said those SIMs had been disconnected. Community posts also described unused credit becoming unavailable and little room to appeal.

What that does not prove. It does not mean every mainland China user was cut off, or that a two-week holiday on giffgaff roaming is now impossible. It also does not mean another UK MVNO will quietly host the same long-term roam pattern. Several people who wrote to ISPreview said they were on temporary work trips or had only recently activated a SIM — so the picture is messy, and individual outcomes vary.

What you should do first. Log into your giffgaff account, read the exact email, and open the current PAC / leaving-giffgaff help article. Do not cancel the account, request a STAC, or “start a new giffgaff” as a workaround if you still need the number. A STAC is for leaving without keeping the number.

We are not repeating alleged clause numbers or quoting emails as if they were statute. If giffgaff cites terms or a fair-use policy in your case, read those documents on giffgaff.com.

Decision tree: keep the number, replace it, or go data-only

Start here before you buy another SIM.

1. Keep this UK number (PAC port). Choose this if banks, HMRC, employers, universities, or long-standing UK apps still send SMS or voice OTPs to that +44. Porting moves the number to another UK network. It does not move leftover giffgaff credit, and it does not guarantee China roaming on the new network.

2. Replace the number. Choose this if the giffgaff line was only a cheap keeper, few services still depend on it, and you can update 2FA destinations in the next few days. A new UK MVNO number, a Hong Kong number you already use, or a secondary US/UK number product can fill different gaps — none of them is a drop-in clone of “old giffgaff + unlimited China roam.”

3. Data-only travel eSIM, keep (or drop) the number separately. Choose this if what you actually need in China is maps, WeChat/WhatsApp data, translation, and hotspot. A China travel eSIM does not give you a UK number and usually does not receive your bank SMS. Pair it with whichever number strategy you picked above.

If you are a digital nomad rather than a UK resident on a short trip, assume one roam SIM should never be the only place every bank 2FA can land. That is the pattern that turns a carrier risk-control email into a lockout.

PAC basics (keep the +44, change the network)

A PAC (Porting Authorisation Code) is the UK switching token that lets another UK mobile provider take over your existing number. Typical flow, at a high level:

Request a PAC from giffgaff while the number still exists in their systems.
Buy or activate a SIM / eSIM with a UK network that accepts inbound ports (VOXI, CTExcel UK, Lebara, and most other UK consumer networks advertise this).
Give that provider the PAC and the number before the code expires.
Wait for the port (often about one working day once submitted; cut-off times are a weekday afternoon theme — check the gaining network).
Confirm SMS and Wi-Fi calling on the new line before you change anything else.

Windows you will see talked about. UK PAC codes are commonly described as valid for about 30 days from issue. giffgaff’s help pages also describe a period after you leave during which you can still request a PAC, plus agent routes if a SIM has been inactive long enough to deactivate. Treat those as themes to confirm on the live help article, not as a promise we can certify for a suspended account.

Self-serve may not work from mainland China. giffgaff’s current PAC article lists text, account settings, and a short-code voice option, and it states that you need to be in the UK to request a PAC that way. If the SIM is already barred, a text from that SIM will fail. People in that situation usually need account login, a help-centre ticket, or an agent — and even those paths can stall. We are not going to invent a “works from China every time” script. If you cannot request a PAC yourself, say so clearly in the ticket and ask for the official process for a disconnected or overseas SIM.

Do not request a STAC if you want to keep the number. Do not close the account first. Credit on the old account typically stays behind; unused balance disputes are a separate complaint track (provider first, then the UK ADR route if you are eligible). That is consumer-process territory, not something a travel-eSIM site can finish for you.

The gaining network still has its own rules. Porting to VOXI, CTExcel, Lebara, Smarty, CMLink, or a big-four brand does not create a right to live on that SIM in China. Many UK consumer brands still describe roaming as travel, not as a foreign primary service. Read the new provider’s fair-use and roaming pages before you port.

Alternatives matrix

Path	What you keep	Best for	Honest limits
PAC to another UK MVNO (VOXI, CTExcel UK, Lebara, and similar)	The same +44	Banks and UK accounts that already know this number	New network T&Cs; China roaming may be limited, expensive, or absent; some brands want UK activation or Wi-Fi calling set up first
Hong Kong number you already use	A +852, not the giffgaff +44	People who already live on an HK line for mainland roaming and local apps	Does not port a UK number; new HK SIMs have their own ID and travel rules
Travel data eSIM (Airalo, Holafly, Saily, Nomad)	Data only	Maps, messaging apps, hotspot, Great Firewall routing that some China eSIMs provide	No UK SMS; not a local Chinese number; unlimited-style plans still have fair-use and hotspot rules
Secondary US/UK number product	A new line for codes and sign-ups	Splitting 2FA and privacy away from a roam SIM	Fresh numbers can fail some banks; short codes / MMS / VoIP rejection still happen — see Saily’s US number for a concrete example

UK MVNO keep-number (VOXI / CTExcel / Lebara-style)

These are the names people search after a giffgaff scare because they accept PAC ports and are easy to buy as eSIM or pay-monthly.

VOXI — Vodafone-network MVNO, built around UK social-data plans. A reasonable port target if you want a mainstream UK app and you will spend time in the UK or on Wi-Fi calling. Treat China roaming as something to look up on VOXI’s current roaming list, not as a reason to pick it.
CTExcel UK — China Telecom’s UK consumer brand (EE network). It is one of the few UK options that markets UK–China calling and roaming to Chinese-speaking customers. That still is not a guarantee your use pattern is allowed, and some community reports say activation is easier in the UK/Europe than in mainland China. Check the live plan page and whether inbound SMS / Wi-Fi calling works on your phone before you move bank 2FA.
Lebara — International-calling MVNO on Vodafone UK. Fine as a PAC destination for a UK number. China roaming on Lebara has been changed in the past; do not assume last year’s “free roam in China” poster still applies.

Other UK names you will see in the same breath: CMLink, Lyca, Smarty, the big four. Same rule: PAC keeps the number; the new contract decides roaming.

Hong Kong number keepers

A Hong Kong SIM is a different product. It can be a sensible data + regional SMS line if you already have one and it roams in the mainland. It cannot inherit your giffgaff +44. If UK banks still text that +44, you still need a PAC or a planned number change.

Travel eSIM for data

If the giffgaff SIM dies tomorrow, you can still get online in China with a prepaid travel eSIM. Start with our China destination page (Airalo, Nomad, and Saily are the usual shortlist there). For how travel data compares with leaving a home line on roam, read travel eSIM vs international roaming. If you are choosing between fixed data and day-based unlimited-style plans, Airalo vs Holafly and Saily vs Airalo are the comparison pages we already maintain.

A China travel eSIM may route some traffic outside the mainland and help with Google or WhatsApp. It will not replace Alipay/WeChat number checks that want a Chinese mobile, and it will not receive your Barclays or Monzo SMS.

Secondary numbers for 2FA

If the job is “receive a code when the roam SIM is dead,” a persistent secondary number is more honest than hoping the next UK PAYG brand looks the other way.

Saily’s optional US (+1) number is the one we have already reviewed on this site: about $0.99/month, inbound SMS included, real cellular number rather than a classic VoIP line, with clear gaps (no MMS, no short codes, local-call-only add-ons, fresh-number risk). Use the in-app checkout and the Saily listing we already use elsewhere; do not treat it as a UK-number replacement.

Whatever secondary line you pick, test it on a low-stakes account first. Move authenticator-app 2FA (or hardware keys) onto banks that allow it before the old SIM goes dark.

Nomad and long-stay angle: split the risk

The fragile setup is: one cheap UK roam SIM holds every bank, Apple/Google, email recovery, and work VPN SMS, while you live in mainland China for months.

A more durable pattern:

Identity line — the +44 you actually need, ported if necessary, preferably reachable on Wi-Fi calling, with authenticator apps already enrolled.
Travel data line — a China eSIM or a regional Asia plan from Nomad / Saily / Airalo, data roaming off on the identity line.
Optional public / US-app line — a secondary number for sign-ups and some 2FA, not your only recovery path.

That is the same split we recommend in the travel eSIM and 2FA guide. The 2026 giffgaff reports are just a loud reminder that the “home line on roam forever” half of the split can fail.

If you are only visiting China for a holiday, you may not need a new UK MVNO at all: keep a working home line for SMS if it is still in good standing, add a travel eSIM for data, and turn off data roaming on the primary. Our UK destination page is for the opposite trip (landing in Britain). For China planning, stay on the China page.

What not to do

This is not a guide to evading a ban.

Do not fabricate UK presence, cycle SIMs under other people’s IDs, or buy “SMS receive” numbers from random grey-market sites to spoof a UK login.
Do not assume a friend’s UK Wi-Fi or a travel eSIM IP makes you a UK-resident customer of a prepaid brand.
Do not dump remaining credit into a last-minute top-up if the account is already under review — several 2026 reports described unused credit staying put after disconnection.

If you primarily live in mainland China, pick a product that is sold for that life: a local or Hong Kong line you are allowed to hold, plus travel eSIMs when you move, plus 2FA that does not depend on one foreign PAYG roam SIM.

FAQ

Is giffgaff banned in China?
There is no public, official “giffgaff is illegal in China” notice that we can point to as of 8 September 2026. What users and ISPreview described is account risk control / disconnection for extended overseas use, with mainland China showing up often in the anecdotes. Confirm your own status in the giffgaff account and email.

Can I still roam in China on giffgaff for a short trip?
Short-term travel is the use case giffgaff says roaming is for. Whether your account is still allowed is a live account question. If you already have a disconnection notice, do not plan a trip around that SIM.

How do I get a PAC from giffgaff if I am in China?
Use the steps on the official PAC article. Self-serve text/call options are described as UK-based. If the SIM cannot send SMS, try account login or an agent. We cannot promise a PAC after a force-disconnect.

Will VOXI, CTExcel, or Lebara accept a giffgaff PAC?
UK consumer networks generally accept PAC inbound ports. You still have to pass their signup checks and complete the port before the code expires. Ask the gaining brand’s porting page, not a WeChat rumour.

Does a travel eSIM keep my UK bank SMS working?
No. Use the home/ported number or a secondary number that the bank accepts. Details: travel eSIM and 2FA.

Should I move every 2FA code to a US number?
No. Use it as a backup or privacy line. Some UK banks will not send to a new +1, and Saily’s US number does not support short codes.

What if I only need internet in China?
Skip the MVNO hunt. Compare China travel eSIMs and, if you care about plan style, Airalo vs Holafly or Saily vs Nomad.
