Troubleshooting
Common issues and solutions when configuring H2O Wireless APN settings.
- No data connection on H2O Wireless
- Ensure the APN is set to 'PRODATA' in uppercase. H2O Wireless APNs are case-sensitive. Set Authentication Type to 'PAP' on Android devices. Toggle Airplane Mode on and off, then wait 30 seconds for the data connection to establish.
- MMS not working on H2O Wireless
- Verify the MMSC is 'http://mmsc.mobile.att.net' and MMS Proxy is 'proxy.mobile.att.net' with port 80. All three MMS fields must be correctly filled. Ensure mobile data is enabled since MMS requires an active cellular data connection.
- H2O Wireless data slow or dropping
- Check that APN Protocol is set to IPv4/IPv6. Toggle Airplane Mode to refresh the network connection. If speeds remain slow, verify you have not exceeded your high-speed data limit for the current billing period. H2O may reduce speeds after reaching your plan's data cap.
