Just popped my o2 Ireland sim card and I was automatically registered roaming on Globe Telecoms network. I then received a greeting from them:
Globe Telecom welcomes you to the Philippines! Thank you for choosing to roam with Globe, the network with the worldwidest coverage. Find out why it’s more fun in the Philippines! Just show this message together with your passport at the Globe Travelers Information Booth in the arrival area of NAIA Terminals 1 and 3 to get a welcome gift from us. If you need help throughout your stay, just call the Globe Hotline at +632730-1212.
