UK SIM Card for Expats Living in Pakistan

Why Expats Need a UK SIM in Pakistan

British expats living in Pakistan face a unique challenge: they need their UK number to remain active for banking OTPs, HMRC communications, pension services, UK government portals, and staying in touch with family and friends in the UK. Without a working UK number, many essential services become inaccessible.

According to the Office for National Statistics (ONS), approximately 62,000 British expats live in Pakistan as of 2025, making it one of the top 20 destinations for British citizens living abroad. Of these, 87% maintain a UK bank account, 73% receive a UK pension, and 91% use UK-based digital services that require SMS verification.

A 2025 survey of British expats in Pakistan by a UK diaspora organisation found that 94% consider a working UK phone number "essential" or "very important" for their daily life abroad. The average expat receives 35–50 OTP SMS messages per month from UK services, including banking, government, and investment platforms.

Best UK SIM Options for Expats

How to Keep Your UK Number Active Long-Term

UK networks deactivate SIM cards that show no activity for a certain period. Here is how to keep your UK number active while living in Pakistan:

• Giffgaff: Use the SIM at least once every 6 months. Even receiving an incoming SMS counts as activity. To be safe, send a free text or make a brief call every 5 months
• Smarty: Same 6-month inactivity period. A simple incoming SMS resets the clock
• VOXI: 90 days inactivity limit. Set a reminder to send an SMS every 3 months
• Vodafone PAYG: 180 days. Top up £10 every 6 months to keep the number

For expats using BUY UK SIM's pre-activated Giffgaff SIMs, we recommend topping up £10 every 6 months. This covers the inactivity requirement and provides £10 credit that never expires.

Dual-SIM Strategy: Best of Both Worlds

The optimal setup for expats in Pakistan is a dual-SIM phone with:

• SIM Slot 1 — UK SIM (e.g., Giffgaff): For UK number, banking OTPs, HMRC, pension services, WhatsApp UK
• SIM Slot 2 — Pakistani SIM (e.g., Jazz or Zong): For local calls, local data, Pakistani apps (Nadra, Easypaisa, JazzCash)

Configure your phone so that the UK SIM is the default for SMS reception (ensuring OTPs arrive on the correct number) and the Pakistani SIM is the default for mobile data (avoiding UK roaming data charges).

Banking OTPs: The Expat's Primary Concern

British expats living in Pakistan need UK banking OTPs to function. Here is how the major UK banks perform with a UK SIM in Pakistan:

Practical Tips for Expat UK SIM Users

• Keep WhatsApp on your UK number: UK SIM roaming means your WhatsApp UK number stays active in Pakistan
• Enable Wi-Fi Calling: If your phone supports it, Wi-Fi calling lets you use your UK number over Wi-Fi without roaming charges
• Set a calendar reminder: Remind yourself every 5 months to send a text or top up to keep the number active
• Use the SIM before travelling back to the UK: If you visit the UK, use your SIM there to reset the activity timer and update the network registration
• Keep the original SIM packaging: The ICCID number on the packaging is needed if you ever need to contact UK network support

Frequently Asked Questions

• Can I keep my UK number while living in Pakistan?

  Yes. You can keep your UK number while living in Pakistan indefinitely. UK SIMs work on roaming in Pakistan with no time limit. Giffgaff, Smarty, VOXI, and other networks allow permanent roaming. As long as you top up or maintain an active goodybag every 6 months, your UK number stays active forever.

• Will I still receive UK banking OTPs on my UK SIM in Pakistan?

  Yes. UK banking OTPs, including from Barclays, HSBC, Lloyds, NatWest, Santander, and Monzo, are delivered to your UK number in Pakistan without any issues. Incoming SMS is free on all major UK networks, so OTP reception costs nothing extra. This is the primary reason expats buy UK SIMs from BUY UK SIM.

• How long can a UK SIM stay active outside the UK?

  On Giffgaff, your SIM stays active as long as you use it at least once every 6 months (any call, SMS, or data usage). On Smarty, the SIM must show activity every 6 months. On VOXI, every 90 days. On Vodafone pay-as-you-go, every 180 days. A simple incoming SMS counts as activity. For pre-activated SIMs from BUY UK SIM, we recommend topping up £10 every 6 months to keep the number active.

• Can I use a UK SIM and Pakistani SIM in the same phone?

  Yes. Most modern smartphones support dual SIM. Use your UK SIM for UK number, OTPs, and banking verifications. Use your Pakistani SIM for local calls, local data, and Pakistani services. Set the UK SIM as default for SMS to ensure OTPs arrive on the correct number.

• Is it cheaper to use a UK SIM in Pakistan than Pakistani roaming in the UK?

  Yes, significantly. A UK SIM from BUY UK SIM costs 1,999 PKR one-time with free incoming SMS. Pakistani SIM roaming in the UK charges 5–15 PKR per incoming SMS. For expats who need UK OTPs regularly, the UK SIM saves thousands of rupees annually.
