Activate Your SIM or eSIM

Welcome to VoIP and SIMs! For your security, all new SIMs and eSIMs are shipped inactive. You’ll need to confirm you’ve received your SIM and request activation before you can use it.

1. Confirm Receipt & Request Activation

Before your SIM or eSIM can be used, please contact us to confirm receipt and request activation. This ensures only you—the authorised account holder—can activate your SIM.

How to Request Activation

By Phone:

Call 0161 507 7999 and select the support option.

Have your order and SIM details ready.

By Email:

Email activations@omnicom.uk with:

  • Your name and contact details (as on your order)
  • Order reference number (from your confirmation email)
  • SIM Serial Number (ICCID) or eID (for eSIM)
  • The mobile number assigned to the SIM (MSISDN), if known
  • For number porting: your PAC code, number to be ported, and preferred port date

2. After You Request Activation

  • Once we verify your details, we’ll activate your SIM or eSIM—usually within a few business hours.
  • You’ll receive confirmation by email or SMS.
  • Please follow the next steps to complete activation.

3. Do I Need to Insert My SIM to Activate It?

  • Physical SIM cards:
    In most cases, you’ll need to insert your SIM card into your device for activation. This allows the network to register and complete the process after we enable it.
  • eSIMs:
    You usually activate your service by downloading a digital profile (scanning a QR code or entering details). With eSIM, your profile can often be set up before you use your device.
  • Some networks may allow online or app-based activation before inserting your SIM. If this applies, we’ll include full instructions with your order.

    When you request activation, we’ll confirm the correct steps for your network and SIM type. If you’re unsure, just ask—our team is here to help!

4. How to Activate an eSIM

Check your device supports eSIM (most new smartphones and tablets do).

Get your activation details from us—we’ll send you a QR code or activation code.

Activate your eSIM:

  • On iPhone: Settings > Mobile Data > Add eSIM or Add Data Plan
  • On Android: Settings > Network & Internet > SIMs > Add SIM
  • Scan the QR code or enter the details provided.

If prompted for an SM-DP+ address and activation code, use the details we supply.

What is SM-DP+?

SM-DP+ stands for Subscription Manager Data Preparation+. It’s just the secure server address your device uses to download your eSIM profile.

In most cases, you won’t need to enter this—just scan your QR code.

If you’re asked, use the SM-DP+ info provided by us, or contact support@omnicom.uk

5. Deploy to Device

For some business users, we can push your eSIM profile directly to your device (Deploy to Device):

  • Make sure your device is on, connected to WiFi, and registered to your account.
  • We’ll notify you by SMS or email when your profile is ready
  • Accept the installation prompt and follow on-screen steps.

6. Still Not Connected?

  • Restart your device after activation.
  • Double-check your SIM/eSIM details and that you’re in a coverage area.
  • For persistent issues, call 0161 507 7999 or email support@omnicom.uk

7. Want to Keep Your Number?

To move your current number to your new SIM or eSIM, mention your PAC code and preferred port date in your activation request, or visit our Get Your PAC Code page.

Thank you for helping us keep your account secure. We’re here to get you connected—safely and quickly.
