Hi there! I understand you’re seeing a “mobile number is invalid” message when trying to use the Greene King Pubs app on your new phone. Let’s see if we can get that sorted out together.

To start, can you tell me:
- Are you entering your mobile number exactly as you did before, including the country code if required? (e.g., +44 for the UK)
- Did you activate or verify your number on the new phone, especially if you may have moved your SIM or number over?
- Have you tried restarting the app or reinstalling it on the new device?

Sometimes, apps require you to re-register or verify your number freshly when switching devices, especially if there’s a built-in security check.

Here are some quick steps to try:

1. Double-check the format: Enter your mobile number with the UK country code (+44), then omit the leading zero. For example, if your number is 07123 456789, enter +447123456789.
2. Restart the Greene King Pubs app and your phone after entering the number.
3. If that doesn’t work, uninstall the app completely, then reinstall it on your new phone. This can clear any old cached data.
4. Ensure your phone number is active on the SIM card and able to send/receive messages, since some apps send verification codes by SMS.
5. If the error persists, there might be an account linkage or server verification step. You can contact Greene King app support or [email protected] for direct help.

Could you try those steps and let me know what happens? If you already tried any of these, please tell me which, and I’ll guide you further from there.

I already tried all of the above

Thanks for letting me know you’ve already tried those steps. Since the mobile number issue persists despite the usual fixes, let’s try a couple of additional checks and then explore next steps.

1. Account Verification Check
Sometimes the system requires the mobile number to be linked with the correct account details on Greene King's side. Have you recently changed any account info, like email or username, that could cause mismatch?

2. Clear App Cache and Data (if possible)
On Windows with WebKit browsing, you might want to clear your browser cache or app data related to Greene King services since cached data can cause validation issues.

3. Test with a Different Network
Try switching the phone’s internet connection from Wi-Fi to mobile data or vice versa to rule out any network-related validation glitches.

4. Attempt Using Another Device or Browser
Since you mentioned a new phone, is it possible to try logging in with the same number on a different device or browser to see if the problem is device-specific?

If none of those help, the issue may lie with backend verification or account status. At this point, I recommend contacting Greene King’s dedicated app support or customer relations at [email protected] so they can look into your account registration and mobile number validity on their side.

Would you like me to help draft a message to them or assist with any of those additional steps? Let me know!
