How to Receive OTP on a UK Number from Pakistan — Step-by-Step

Which Platforms Send OTPs to UK Numbers?

A working UK SIM receives OTPs from: WhatsApp, PayPal, TikTok, Wise (TransferWise), Binance, Telegram, Discord, Instagram, Facebook, Snapchat, Google (Gmail), Microsoft, Apple ID, Amazon, eBay, Upwork, Fiverr, LinkedIn, Twitter/X, and many more. The key requirement is a genuine physical UK SIM on a real mobile network — virtual VoIP numbers are blocked by most of these platforms.

Step-by-Step: Testing Your OTP

1. Insert your UK SIM and wait for network signal
2. Open any app that requires phone verification (WhatsApp is the easiest test)
3. Enter your UK phone number (include +44 country code, drop the leading 0)
4. Tap "Send Code" or "Verify"
5. Wait for the 6-digit SMS to arrive (usually 10-60 seconds)
6. Enter the code to verify

Why Some SIMs Do Not Receive OTPs

Several reasons: the SIM is TikTok Live-only (configured only for data, not full SMS), the SIM was not properly activated on the UK network, the SIM has been deactivated due to inactivity, the SIM is a virtual/VoIP number being blocked by the platform, or your phone's SMS settings or network configuration is interfering. This is why we recommend buying from sellers who explicitly guarantee OTP delivery, such as uksimpakistan.store, whose Giffgaff SIMs are sold specifically for OTP compatibility.

Troubleshooting OTP Problems

• Wait — some networks take up to 2 minutes to deliver international SMS
• Toggle airplane mode on and off to refresh network connection
• Restart your phone
• Try manual network selection (Settings > Network Operators > Manual)
• Clear the app cache and try again
• Try a different app — if WhatsApp OTP arrives but PayPal does not, the issue may be with PayPal, not your SIM
• If no OTP arrives from any app, your SIM may be defective — contact your seller

Dual SIM Setup for OTP

Many Pakistani users keep their Pakistan SIM in SIM slot 1 (for local calls and data) and the UK SIM in SIM slot 2 (for OTP receiving). In your phone settings, set SIM 1 as default for calls and data, and SIM 2 as standby. When an app requests verification, make sure you enter the UK number (SIM 2 number). The OTP will arrive via SMS on SIM 2 regardless of which SIM is set as default for data.
