How to set up APN settings for SAMSUNG S21

[HopefulChicken]

2 hours later here is what I figured out…

Open Settings on your phone (swipe down twice and hit the gear icon for Settings)

Follow this path:

Settings - More… (Airplane mode, Tethering, VPN) – Cellular Networks – Access Point Names (APN)

Once in APN hit the “kebab setting menu” (three vertical dots on the top right) then hit -Reset to default

My phone had a Koodo and TELUS APN settings come up, ignore them and hit the “+” (top right with a circle around it) and then manually input the following APN settings (please make sure it is all exact even upper- and lower-case letters):

Name: Public Mobile

APN: sp.mb.com

APN type (select each one): default, mms, supl, wap, net

Proxy: not set

Port: not set

Username: not set

Password: not set

Server: not set

MMSC: http://aliasredirect.net/proxy/mb/mmsc

MMSC proxy: 74.49.0.18

MMS port: 80

MCC: 302

MNC: 220

Authentication type: Not set

APN protocol: IPv4/IPv6

APN roaming protocol: IPv4/IPv6 

APN enable/disable: APN enabled

Bearer: Unspecified

MVNO type: GID

MVNO: 4d4f

Once all info is correctly manually entered hit the “kebab setting menu” (three vertical dots on the top right) hit SAVE

Then Press and hold the power button on the outside of your phone then select – Power off and let your phone power down (I tried using Restart and it did not work)

After your phone is powered down turn it back on and data and picture texting should work.

I hope this is helpful to someone else.

Usually the APN will come down automatically.  Maybe a reboot once or twice with couple minutes wait is all it needs

Nice post. Did your data not work previous to you editing the APN? Is your phone CPU? Samsung phones normally populate the appropriate APN after inserting the sim card. Often the APN will list telus or koodo as the provider but the APN will still work for public mobile.
