Zone 1 data

[Segy]

Please can you help me use my data in zone 1 USA starting ASAP? Thanks

@Segy This is not O2. This is a customer community. See if these guides are of use to you:

USA - Roaming with O2 - O2 Community

Roaming on O2 - All you need to know - O2 Community

If you're still having difficulty you can reach O2 via social media:
Facebook (https://o2uk.co/O2CFB), Twitter (now X) (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)

Try manually switching between T-Mobile and AT&T to see which works best.
