BuyUKeSIM - Best for UK Number & SMS Verification
BuyUKeSIM is the only provider in this comparison that gives you a real UK +44 phone number with unlimited incoming SMS. This makes it the best choice if you need a UK number for:
- WhatsApp, Telegram, Signal - register and verify with a real UK number
- PayPal, Wise - fintech verification
- Google, Instagram, Amazon - 2FA and account recovery
- Privacy - no KYC, no account, pay with crypto
BuyUKeSIM does not include mobile data on the $25 UK Number line (SMS and incoming calls only). For trip data we sell a separate Travel eSIM product - crypto checkout, no KYC, country packs from Turkey to Global. Price: $25 per UK Number eSIM, one-time payment with crypto.
BuyUKeSIM Travel eSIM - crypto travel data
Since 2026 you can also buy prepaid roaming data on the same site. No UK phone number on that product - it is purpose-built for maps, messaging, and mobile internet abroad. Ideal if you already use BuyUKeSIM for +44 verification and want one wallet for both. Guide: Travel eSIM with crypto (2026).
Airalo - Best for Travel Data
Airalo is a popular travel eSIM marketplace. They sell data-only eSIMs for 200+ countries, including the UK. Airalo is great if you need mobile internet while traveling in the UK, but:
- No phone number included - you cannot receive SMS or calls
- Cannot verify WhatsApp, Telegram, or PayPal
- Requires an account with email
- Payment by credit card or PayPal only
Airalo is ideal for travelers who need data. It is not a replacement for a real UK phone number.
Holafly - Best for Unlimited Travel Data
Holafly offers unlimited data eSIMs for travelers. Their UK plan gives you unlimited 4G/5G data for a daily rate. Like Airalo:
- No phone number - no SMS, no calls
- Cannot use for verification or 2FA
- Requires account and personal details
- Credit card or PayPal payment
Holafly is a solid choice if you are visiting the UK and want unlimited internet. But if you need a UK phone number, it is not the right product.
Which Should You Choose?
| I need... | Best choice |
|---|---|
| A real UK +44 number for SMS verification | BuyUKeSIM |
| WhatsApp/Telegram registration with UK number | BuyUKeSIM |
| Anonymous UK number, no KYC | BuyUKeSIM |
| Pay with crypto (USDT/TRX) | BuyUKeSIM |
| Mobile data while travelling (crypto, no account) | BuyUKeSIM Travel eSIM |
| Mobile data while traveling in UK (card OK) | Airalo or Holafly |
| Unlimited data for UK travel | Holafly |
| Cheapest UK data plan | Airalo |
Can I Use UK Number + Travel Data Together?
Yes. If your phone supports dual eSIM, use BuyUKeSIM for your UK +44 number (SMS and calls) and either BuyUKeSIM Travel eSIM or Airalo/Holafly for data. Using BuyUKeSIM for both keeps crypto checkout and no-KYC policy on one site.
Conclusion
Airalo and Holafly remain strong card-based travel data options. BuyUKeSIM is the only option here that provides a real UK +44 number with incoming SMS, and now also sells Travel eSIM data with crypto. If you need verification + anonymous checkout, BuyUKeSIM is the clear winner for the number; for data, compare our Travel eSIM packs against their catalogs.
