The Porting Process

1

Request your PAC Code

Text "PAC" to 65075 from your current network provider. They must reply within 60 seconds with your 9-character PAC code.

2

Give it to SecondSim

Purchase your SecondSim subscription and contact our support team with your PAC code and the number you wish to port.

3

Wait for Transfer

Transfers typically happen on the next working day. You'll experience a brief loss of service before your old number activates on your new SecondSim eSIM.

Troubleshooting & Common Fixes

My QR code won't scan. What should I do?

This usually happens if your phone camera cannot focus or if you are trying to scan the code under direct glare. You can install manually: tap Enter details manually on the Add eSIM screen and copy-paste the SM-DP+ Address and Activation Code provided in your welcome email.

The SMS verification code from WhatsApp is not arriving.

First, verify that your eSIM line is turned ON under Settings > Connections > SIM Manager. Second, check that you have mobile reception (look for the dual signal strength bars in your top status bar). If you are currently traveling outside the UK, ensure you have enabled Roaming on your eSIM to allow incoming SMS delivery.

Why are my personal and business contacts merging?

Unlike iPhone, Android allows you to filter contact directories. By default, both WhatsApp apps pull from the same main Google Contacts list. To separate them:

  • Open your Contacts app and create a label called "Business".
  • Assign all clients and work leads to this label.
  • In WhatsApp Business, you can choose to only display or chat with contacts that have this specific label, ensuring friends and clients don't blend.

Will a SecondSim eSIM get my WhatsApp account banned?

No. WhatsApp actively bans virtual numbers (VoIP) because they are commonly used by spammers. Because SecondSim operates on standard Tier-1 mobile networks, our eSIMs issue real carrier numbers. They bypass WhatsApp's anti-fraud system first time, giving you long-term security.
