How do I setup data and APN on my Android phone?

[Lachlan_M]

If you’re having trouble with data on your Android smartphone, you may need to configure your network settings for Public Mobile. The steps below may not be exactly the same on your particular phone but they should help you to get going.

Step1: 

Android 2.3 and lower 

Settings > Wireless & Networks > Mobile Networks > Access Point Names > New APN setting (or a plus sign)

Android 4.0 and higher 

Settings > More... > Mobile Networks > Access Point Names > New APN setting (or a plus sign) *Some models might have a slightly different path 

Step 2: 

You will need to input the following info:

Name: Public Mobile
APN: sp.mb.com
Proxy: Leave blank
Port: Leave blank
Username: Leave blank
Password: Leave blank
Server: Leave blank
MMSC: http://aliasredirect.net/proxy/mb/mmsc
MMSC proxy: 74.49.0.18
MMS port: 80
MCC: 302
MNC: 220
Authentication type: Leave blank
APN type: Leave blank

Step 3:

Select Save/Done. Select Public Mobile to connect to the Public Mobile network. Your data should work normally now.

Do you have LTE as preferred network type in your settings?

I have a One Plus One phone and I setup the APN according to you post and I got H+ istead of LTE. Is that right?

This is the first time I had to use Access point names to setup data on my Nexus 5.
I am providing the Path for other Nexus 5/ android 5.1 users to make it easier
Settings>...More>Mobile networks>Access point names>(enter the fields shown above)
Now data works !
