Global eSIM

From £6/month (goodybag plans; data allowance given as 2–3GB depending on source); eSIM is free

At least one chargeable activity every 6 months: call or text another number, use mobile data, or buy credit or a plan (calls to customer service, 0800 or free numbers don't count). Reminder emails about 1 month and 5 days before the deadline; within 30 days of deactivation you can ask customer service for a PAC to port out, after which the number is reclaimed and can't be recovered

Account registration needs an email address and a payment card; no ID needed for monthly or 18-month contract eSIMs (handset finance has a separate credit check, not verified separately)

Official roaming rates: in the rest of the world, receiving texts is free, sending costs 30p per text, answering calls £1/min; unlimited texts within plan in 37 EU destinations. Wi-Fi Calling/VoLTE opened to all customers in 2024, but official guidance says Wi-Fi Calling doesn't work abroad

Main UK number and cheap number keeping; long-term residents abroad risk disconnection

Rolling monthly plans about £1–3/month on promotion, normally from about £4.90/month (HotUKDeals 2026 deal posts; prices change often)

Terms (as quoted on the ISPreview forum, version effective 2025-08-20): after 90 days with no chargeable activity (calls/texts/data) the balance is cleared and the SIM temporarily deactivated; topping up or buying a bundle within the following 365 days restores it, after which service is disconnected and the SIM can't be used again. A Lebara community manager confirmed on 2026-09-16: ‘temporarily deactivated after 90 days of non-use, can be reactivated within a further 365 days, then permanently deactivated’. Some users received reminder emails saying the SIM expires after 215 days of inactivity, while customer service says 90 days; accounts differ

Order online; a comparison table from Roami (a travel eSIM seller; published 2026-09, updated 2026-10) says Lebara online purchases need no ID or UK address, but the same article warns that non-UK billing addresses or foreign cards are often rejected by UK fraud checks; Lebara's official terms not checked directly

Holafly (data as of 2026-10-15) lists Lebara pay-per-use roaming rates: receiving texts free, sending 49p per text, answering calls 49p/min; applies outside Roam Like Home destinations (e.g. US, Hong Kong) when no roaming bundle has been bought (third party; the official lebara.co.uk page returned 403 and couldn't be opened). Users on r/LebaraUK also say customer service told them receiving texts in the US is free. Wi-Fi Calling supported (kenstechtips 2022 table, older source)

Cheap UK number; EU/India roaming

Rolling monthly bundles from £5/month (first-month price, rises afterwards; 2025 data); minimum top-up £10 for plain PAYG (2026-04 blog)

FAQ (as quoted in a blog): the number is reclaimed after 120 days of non-use; dialling *139*9999# extends this to up to 1 year for a £15 annual fee taken from credit. The blogger's method: top up £10 once, then every ~119 days send one 23p text or use 1MB of data (15p) to keep the number

No contract, no credit check; order online

Standard roaming rates (via Holafly, data as of 2026-10-15): the US is in Zone 2, sending texts £0.48 each, answering calls £0.25/min, making calls £0.80/min; the table header charges only for ‘outgoing texts’ and lists no price for receiving, and nothing explicit was found on whether receiving is charged.

China Unicom (Hong Kong) (MVNO, mainly on the 3HK network, among others) · Prepaid

Hong Kong SIM for travel to and from mainland China

A first purchase of a bundle over HK$50 comes with a free eSIM (e.g. HK$38 mainland and Macau data + HK$15 Asia data pass = HK$53); physical SIMs are only posted to Hong Kong addresses

Buy any paid service again within 365 days of the last purchase and the number's validity is extended by 1 year from the purchase date. The old HK$6 SMS pack has been withdrawn (around 2026-06-30; some say it rose to HK$28); the current minimum is about HK$15/year (Asia data roaming pass)

Real-name registration in the app: photograph a passport or Exit-Entry Permit for Travelling to and from Hong Kong and Macao (choose ‘other travel documents’) for recognition and submit; usually approved quickly; each person can have at most 10 numbers with this operator, and expired numbers can be de-registered on the official site to free up slots

Several blogs say receiving texts in mainland China is generally free; users say it works for registering Telegram, WhatsApp, cross-border e-commerce and banks, but some AI platforms (ChatGPT and Claude were named) don't deliver codes or won't allow registration. The official terms of the HK$15 data pass exclude international SMS and roaming voice

Initially valid for 12 months after activation, extended by top-ups: €5 adds 4 months; several €15 top-ups or a single €30 top-up give up to 24 months; after expiry there are about 2 months in which you can only receive calls and SMS, then the line is deactivated. To take the number with you, you must formally cancel

German law (§172 TKG) requires identity verification before any SIM/eSIM is activated; a passport can be used (foreign passports depend on the verification provider, and some may be rejected); on a phone, verify by video in the app (24 hours) or at one of about 10,000 partner stores via Shop-Ident; residence registration is not required, a temporary German contact address (a hotel is fine) is enough
