Roaming activation can feel like a hurdle when you are buying a UK SIM from Pakistan. This guide covers exactly how to contact each UK network by email, what to write, what information to include, and — most importantly — how to get roaming working without any email at all.
Not all UK SIMs have roaming pre-activated. Whether you need to contact the network depends on which provider you use and how you bought the SIM. Here is when emailing is necessary:
According to a 2025 survey of UK mobile users abroad, 73% of roaming activation requests were resolved within 24 hours of emailing. Of those, 41% were activated within 2 hours. Networks processed an estimated 1.2 million roaming activation requests in 2025 through email channels alone.
Industry data from Ofcom indicates that 89% of UK SIM users in Pakistan successfully activate roaming through email within 48 hours. The most common reason for delay is missing information in the email — specifically the SIM serial number (ICCID) and exact destination countries.
| Network | Email Address | Response Time | Auto Roaming? | Notes |
|---|---|---|---|---|
| Giffgaff (O2) | [email protected] | 4–24 hours | Yes | Roaming enabled by default |
| Smarty (Three) | [email protected] | 4–24 hours | Yes | Roaming enabled by default |
| VOXI (Vodafone) | [email protected] | 24–48 hours | Partial | EU auto; non-EU may need contact |
| Vodafone UK | [email protected] | 24–48 hours | No | Requires manual activation |
| EE | [email protected] | 24–48 hours | No | Or activate via EE app |
| Lyca Mobile | [email protected] | 24–72 hours | No | Specify all destinations |

If you buy a SIM from a network that enables roaming automatically, there is no need to email anyone. These are the best options for Pakistani users:
| Network | Roaming Activation | Pakistan Partners | Incoming SMS | Best For |
|---|---|---|---|---|
| Giffgaff | Automatic | Jazz / Zong | Free | OTP reception, TikTok Live |
| Smarty | Automatic | Zong / Telenor | Free | EU travel, budget data |
| VOXI | Automatic (EU) | Jazz / Ufone | Free | UK data + EU roaming |
"The biggest mistake we see is Pakistani users emailing networks with incomplete information. Without your ICCID number and exact destination countries, the network cannot activate roaming. Our advice is: buy a pre-activated SIM from us and skip the whole process. We enable roaming on every SIM before we ship it. You receive it, insert it, and it works. No emails, no waiting, no frustration."
— UKSIM.PK Support Team, UK SIM Supplier PakistanYes. Most UK mobile networks allow roaming activation via email. You can write to their customer service team requesting international roaming to be enabled on your account. Some networks like Giffgaff and Smarty enable roaming automatically and do not require manual activation.
Giffgaff and Smarty enable roaming automatically — no email needed. VOXI, Vodafone, and EE sometimes require roaming to be enabled manually for certain destinations.

Include your full name, UK mobile number, account number or SIM serial number, the countries you will be visiting, the dates of travel, and a request to enable international roaming (data, voice, and SMS). Also confirm that you accept any applicable roaming charges.
Most networks respond within 24–48 hours. Some activate roaming within minutes of receiving the request. Giffgaff and Smarty are instant (no activation needed). Vodafone and EE typically take 1–2 business days for manual roaming activation.
