Here is my guide to Roaming. This is my understanding of what the charges are.
If anyone spots any errors then please let me know and I will correct it.
Roaming Area | Roam-Free | Global Plus | Roam Further |
Countries/Region Calling to | 51 | 30 | 100 |
UK | UK Allowance | UK Allowance | £6 + UK Allowance |
Roam Free Countries | UK Allowance | Charge you pay in UK | £6 + Charge you pay in UK |
Country You are Roaming | N/A | UK Allowance For Calls within Roaming Country | £6 + UK Allowance For Calls within Roaming Country |
Rest of the World | Charge you pay in UK | Charge you pay in UK | £6 + Charge you pay in UK |
Note: Global Roaming is now only available on Unlimited Max or Unlimited Max with Entertainment. For all others the Roaming charge will be same as Roam Further.
For countries that don't fall in this category, will be at Standard Roaming rates or No Roaming allowed.
