H2O wireless APN configuration

This is how we got our H2Owireless SIM working. The configuration is not automatic - some manual work might be required. Here are the steps that worked for us:

  1. Activate the SIM online on their website.
  2. Insert the nano-SIM in the phone.
  3. Initially calls and SMS might work - LTE data might not work.

If your connection or data is not working by now, then follow these steps:

  1. Need to add their APN settings (one time configuration). Follow guide here - How and Why to Configure APNs
    4.1 Goto Settings > Network & internet > Mobile network > Advanced > Access point names
    4.2 Click on ‘+’ to add a new APN
    4.3 Enter these settings (they are case-sensitive):
  NAME: H2O Internet
  MMSC: http://mmsc.mobile.att.net

  MMS Proxy: http://proxy.mobile.att.net
  MMS Port: 80
  MCC: 310

  MNC: 410
  Authentication Type: None
  APN Type: default,mms,supl
  APN Protocol: IPv4

Now click on 3-dots in top-right and hit “Save”

Select H2O Internet (as shown in picture)

Test connection
Disable wifi to make sure LTE icon shows up. Calling, sms and internet should all work.
