Re: How do I know if my phone will work on the Public Mobile network?

@DallasL having a hard time finding specs for that specific variant (ending in "M").  Do you know what carrier sold it originally?  Also:  could it be locked to your previous carrier?  The statement from the moderator is a bit perplexing, but if the phone was carrier-locked (to anyone but Telus or Koodo), that might be intepreted as "not approved".

Re: How do I know if my phone will work on the Public Mobile network?

Thankyou for your responces Carld123 and srlawren! I apreaceate it.

@srlawren the M simply denotes the canadian edition of the phone, otherwise it is the same as the regular S3 SGH-i747 (i747M is the Canadian version. 1747 is AT&T's version)

 

I have an S3 with Liniage OS installed that is also unlocked (though it doesnt show up right) and access to an S3 with stock Rom (curently with Virgin) that is confirmed unlocked. Both were originaly with Koodo, both can phone out using the virgin SIM. Both will not conect to the PM network.

The modorator said "...even if the device supports some or all of the required frequencies, it will not be able to connect unless the device is approved for our network."

From searching the forums, it looks like other members have used S3s in the past anyway. I would be intorested to know if anyone still is.

Re: How do I know if my phone will work on the Public Mobile network?

@DallasL I've never heard of a device not being authorized for PM use--incompatible yes, locked elsewhere yes, but not "unathorized".  OH wait.... could it have been added to the blacklist?  Check your IMEI using PM's checker here:  https://www.publicmobile.ca/en/bc/get-started.  It's not useful for compatbility, but is for checking blacklisting.  You should also check here: https://www.devicecheck.ca/check-status-device-canada/.

Re: How do I know if my phone will work on the Public Mobile network?

Checked now at both links, all turns up ok. It would be wierd for both phones to sudenly be marked. (original owers being myself and my Dad).

In other parts of the message he did use the term "not compatable". Is it bad form to posta coppy of a privet message? I am just guna do it for clarity, as there doesnt seem to be any sensitive data in it:

The reason why you didn't receive your 6 digits code is because your phone is not connected to the network.

Your phone is not compatible with the Public Mobile network. It can be unlocked but still not compatible with the Public Mobile network.

 

Public Mobile works on following frequencies:

 

For 3G use (UMTS/HSPA): 850MHz/1900MHz bands.
For 4G/LTE use: 1700MHz/2100MHz bands.
However, even if the device supports some or all of the required frequencies, it will not be able to connect unless the device is approved for our network. 

 

On the Public Mobile website, a disclaimer is displayed just below the section where you enter your IMEI of your device, stating this following message : 

 

Disclaimer

This information is indicative only. Your device's compatibility with our 4G or 4G LTE networks is based on the radio frequencies of your device. Public Mobile does not guarantee that your device will work on our mobile network.

We do not guaranteed his compatibility.  I highly recommend you to try the phone with a Public Mobile SIM card, if possible, before purchase it.


 

This just seems realy strange to me.

Re: How do I know if my phone will work on the Public Mobile network?

@DallasL it is very strange.  There's no reason a network-compatible variant of an S3 shouldn't be able to work.  It's an old phone but was a very popular handset when it was current. 

 

I think the moderator is misinformed.  @Mary_M sorry to bug you but can you maybe review the info @DallasL has received from one of the moderators?

Re: How do I know if my phone will work on the Public Mobile network?

@DallasL, what happens exactly when you power up the phone with a PM SIM? Emergency calls only? Some other message? Any bars visible? Is it set to automatically detect a network and use all technologies (3G/4G)?

 

If it's available, you can try to change the CSC. It works on some older Samsung devices. This will factory reset your phone and erase all content, so please backup important info.

 

*#272*IMEI#

Where IMEI is a unique identifier of your phone, can be found by dialing *#06#

You can change the CSC to TLS (Telus) to see if it helps.

 

The moderator is giving you some bad information.

 

Last question, have you confirmed the PM SIM is active and functional by using it in another phone?

Good Citizen / Bon Citoyen

Re: How do I know if my phone will work on the Public Mobile network?

@sheytoon Thanks for chipping in!

I am not familier with what the CSC is. I tried dialing *#272*IMEI# on my Liniage OS (Android 7) S3 and nothing happened? Or is that somthing that would only do somthing on the stock rom? I had to send my dads phone back to him, but I think I might be able to try one of my inlaws unlocked LG G3s tomorw.


My S3 shows no bars, and says "Emergancy calls only", and Preferred network type is set to "GSM/WCDMA/LTE".

In the mobile networks settings the one phone (Stock Rom) when I searched for network oporators I can see Public mobile but when I try to conect it says "failed to conect, try again latter". (If my memory serves corectly I think it was showing full bars with the Public Mobile card? but that may not be right.) On the other phone (Liniage OS 7) it says "Error wile conecting to network."

Re: How do I know if my phone will work on the Public Mobile network?

Thanks for the info!

 

The CSC is a carrier-specific customization that Samsung had in the past. On some models, it was allowed to be changed by the customer. It would only work on stock Samsung (if at all). I forgot you had Lineage on one of them. So that's probably not the issue.

 

Right now I'm thinking the SIM card is not activated properly. It seems like an authentication failure with the network. Your best bet to narrow it down is to try the SIM in another phone model.

 

If you have a lot of time and want to try something out of the box, you can also try installing Network Signal Guru on a rooted device that has a Qualcomm chipset. Here's the app:

https://play.google.com/store/apps/details?id=com.qtrun.QuickTest

 

I assume you're rooted since you've changed the OS already. If it does work and you get access to the modem diagnostics, scroll to the signaling page and let me know if you can see messages being exchanged with the network. I can help decode them.

Re: How do I know if my phone will work on the Public Mobile network?

@sheytoon

I tried to get the 6 digit pin on my inlaws LG G4 this morning, but nothing so far. It shows full bars, and in the "Network Oporators" settigns there are two public mobile options: "RAT: LTE", and "RAT: WCDMA". I didn't know what to chose so I just selected "Select automatically". After a wile I got a mesage saying: "Your SIM card does not alow access to this network".

 

I then tried the WCDMA option, and after the "Registering on Public Mobile..." loading animation spun for a wile I again got a "Your SIM card does not alow a conection to this network".

 

So I tried the LTE option and got the same.

I am trying Network Signal Guru on my S3 now. I am not 100% sure how the app works. It looks more like a live monitoring app than one that runns times tests. Is that right? Right now It looks like most of the signaling page messages are about the device itself rather than the network. SystemInformation-BCH and MasterInformationBlock messages. (Update: over the last hour+ the only variation on "SystemInformation" and "MasterInformation" messages are various "Paging Type" mesages.) I will continue to keep it running and post an update if I see somthing new. 

Is there any chance I might have a faulty SIM card?

Re: How do I know if my phone will work on the Public Mobile network?

It sounds like the SIM card is not properly provisioned.

 

You should see some messages with RRC in the beginning (i.e. RRC CONNECTION REQUEST, RRC CONNECTION SETUP, etc).

 

It's possible Network Signal Guru (NSG) doesn't fully support your phone's modem. NSG is a diagnostics tool and provides helpful information for network troubleshooting. RAT means Radio Access Technology (i.e. 2G/3G/4G, and soon to be 5G). PM supports both WCDMA (3G) and LTE (4G).

 

SIB is System Information Broadcasts. These are messages broadcast from the base station (tower), and it's one of the first messages a phone will decode in order to find out where it is (which network, which technology, which frequency, etc). After MIB/SIB messaging, your phone should request to attach to the network with a series of RRC messages. This will always happen, regardless of SIM status. If you don't see these messages, it might be a limitation of NSG for your phone's modem. Once you are able to view RRC messaging, you can see if the network is accepting or rejecting your request. If you are rejected, the phone will go to emergency only, and usually will not show any bars on the screen. You can toggle airplane mode on/off to force the attach procedure.

 

You can ignore paging messages. That's for the network to page all users under a certain Tracking Area, and the network will ask one specific user to "wake up" in order to receive an incoming call or data session. This is how incoming services are delivered when a user is idle.

 

I would bug the moderator team again while you're waiting for another phone to test. They should do a better job confirming the status of SIM provisioning.
