Mobile Data will not work anymore for internet connection

[Kona42]

Hi, 

I have an Android phone - Ulefone X12 Pro 

The Mobile Data stopped working about a month ago.  I can text and make phone calls only and use the Wifi No issues. 

I noticed my plan has 4 G.  My phone is set to 3 G.  If I set it to 4 G nothing works.  I wonder if maybe my Sim card is too old ?  If I order a new card what happens to my phone number etc? 

I tried the following:  Restarted my phone, turned Airplane mode on and off, turned Wifi off. And removed my SIM card and put it back in. Nothing has helped.

No APN settings on my phone so cannot do that part. 

What do you think about trying to do the reset for the wireless, bluetooth and mobile data setting on my phone? I thought maybe that would work. 

Any suggestions would be great! 

Thanks all 🙂

HI @Kona42 

first, data issue has nothing to do with VoLTE.  VoLTE is for voice.  If voice is working and you have data problem, just ignore the VoLTE list for now

according to the spec here:
https://store.ulefone.com/products/armor-x12-pro?srsltid=AfmBOooEAWnxxIAflZFBj4yyovqCIn6V2czGFtvozhE...

your phone have some of the required band on 4G, and it worked before

I would try Reset Network settings first

If the Reset didn't help, then manually update the APN.  Have patience making the changes as this may require a little time of trial and error. 

APN: SP.MB.COM
MMSC: http://aliasredirect.net/proxy/mb/mmsc
MMS Proxy: mmscproxy.mobility.ca
MMS Port: 8799
MCC: 302
MNC: 220
Authentication Type: Not Set
APN Type:   default,mms,agps,supl,fota,hipri     
APN protocol: IPv4
APN roaming protocol: IPv4
APN enable/disable: APN enabled
Bearer: Unspecified
MVNO (Mobile virtual network operator) type: GID
MVNO (Mobile virtual network operator)value: 4D4F

I have been using this phone since last March on the 3g Network with 

Public Mobile. It has only stopped working on data for about a month or so.

My plan is for 4 g.

SIM card cannot be 'old'.

Have you Ever been able to use data (internet) with PM service AND with your current phone?
Maybe you ran out of data?
If you do have data available try to check your SIM in any other phone to determine if issues is with PM service or your phone.

Your phone is not designed for use in North America. The phone only has compatible bands on 3G but not 4G.  So, you will have to change phone to one that is compatible or stay with 3G network

@Kona42 

sounds like you should upgrade to a new cellphone that is on the Public Mobile whitelist of VoLTE certified cellphones. 

edited...ignore my reply....as pointed out by hTideGnow , lack of access to data isn't a VoLTE issue.

TELUS, Public Mobile’s Parent company, is currently refarming the 850MHz band 5 spectrum to enhance our 4G and 5G network. This involves testing and potentially altering how your device uses the 850MHz (band 5) on LTE and the 1900MHz (band 2) on 3G/HSPA.

You just need to make sure you have a phone that can work on Public Mobile.

To confirm if your phone will work with Public Mobile, please see this link. These are currently and mildly out of date lists of what can work. There have been reports other phones not on this list may work.

You can TRY to reset your Network Settings however, because the phone is not on the approved VoLTE list, it makes things a tad hard to deal with.
