I have only one APN (sp.mb.com) set up on my Nexus 5, and tethering works without a hitch.
Also, http://tamingthedroid.com/what-apn-settings-mean says:
"Other APN types that exist include "supl" for a feature called "Secure User Plane Location", a feature of Assisted GPS. This APN type usually doesn't need to be specified and Assisted GPS will still work correctly. Another is "dun" for dial-up networking, however this refers to an outdated method for using your phone to emulate a dial-up modem and is not the way that modern smartphones do tethering anymore.
Some websites recommend adding even more values to these fields, however in normal cases (unless you have been advised by your carrier to use a certain value) these will have no effect at all: "default" or "*" is a suitable catch-all. In particular, specifying "hipri" does not improve the performance of your internet data, despite claims by many websites."
Have recently help a few friends with this and here's what worked. Lines marked with "*" vary from prior guidance given herein and/or are the setting RECEIVED from PM network once a successful data connection is established.
THE GOTCHA'S ...
With regard to "APN type" parameter, the specification says that "a default APN MUST BE DEFINED;" therefore, setting this parameters to "default" is important. If you have multiple APNs listed, ONLY one, the PM one, should have the APN type "default".
Including "mms", as in, "default,mms" makes it clear TO THE PHONE to route MMS via this APN/carrier. IT APPEARS CRITICAL THAT there are NO SPACES between the words and the commas (e.g. "default,<space>mms" = wrong and "default,mms" = correct). A trailing space proved an issue on a phone (e.g. "default, mms<space>" = wrong and "default,mms" = correct). Like "default", only the correct and active APN should include the "mms" tag.

I have tried every configuration of APN settings I've seen on this forum and on other sites on my Samsung S6 (SM-G920F global model) and am having no luck. I've deleted all old ones as alluded to in the post above - I have no conflicting APN settings. Tried all different options of APN Type etc. etc. to no avail.
Can anybody help me here please? Not a great start to my relationship with Public Mobile, I have to say.
Confirming,,, one only APN choice in the Access Point Names "folder," right? This one only choice is presently set as shown in my post, "Mobile Internet/sp.mb.com", right? And you've verified no trailing spaces following ANY entry, right? This *@%! gotcha is too easy to miss given that the keyboards auto space.
The above being true, you have then rebooted your phone and then waited; I've seen it take a quite few minutes to acquire the LTE (or 3G) indicator on first handshake. It's near instantaneous once it's working. I've seen where this full reboot is needed because Network ON to OFF to ON is insufficient.
Other things to try,,,
Data Roaming = ON
Preferred Network Type = LTE
Available Networks = Public Mobile
Available Networks = "Automatically choose preferred network" is the the preferred setting, but you may need to hit the nail more squarely to get first handshake. After first successful handshake, you may set this back to automatic.
The MVNO parameters shown are AS THEY GET SET TO BY THE NETWORK upon successful handshake. You may try leaving them as "Unspecified". But, in any case, different MVNO values from those shown may be prefectly correct for your operating regions and frequency bands.
And, under the just making sure heading,,,
You have to SAVE the parameter values. SAVE is done via the MENU selector in the upper righthand corner. Then you have to SELECT this APN. Then you reboot.
@s2scotty - Thank you!! I've been with Public two months now and I finally got MMS working thanks to your advice.
What I added in order to make MMS sending work:
APN type: default,mms (no spaces before, after or inbetween)
MVNO type: GID
MVNO value: 4d4f
Then I reset.
They really need to update the original post... @Shazia_K?
Hey, i have an HTC one M7 and i do not have the option for a mmsc PORT, will everyhting work fine anyways?
