GPS Time Reset Issue Impacting Location Accuracy on Select Phones

Hey Community, 

 

Public Mobile has identified a small number of select devices that, as of April 6th, 2019, will no longer provide accurate location functionality. These devices may, however, obtain some location functionality through wireless tower triangulation so Emergency Services may continue to get locations for these customers.

 

Public Mobile will communicate to all impacted customers to make them aware of this issue and encourage them to download the applicable software patch to their devices to resolve this issue.

 

Public Mobile has worked with manufacturers to roll out fixes to affected devices. If your device is listed below, please update your devices to the latest software.

  • Alcatel A50 (5085O)
  • Alcatel 1 (5033O)
  • Alcatel Lume (A466T)
  • Alcatel Pixi 3(4) (A460T)
  • Alcatel Pixi 3(4.5) (5017O)

 

Some devices, however, will not receive software patches due to their age. If your device is listed below, please be aware of this issue and exercise caution if you find yourself in a 911 situation. Alternatively, you can purchase a new device.

  • Alcatel A392A / A392CC
  • Alcatel Idol X+ (6043A)
  • RIM BlackBerry Curve (9320)
  • RIM BlackBerry Curve 3G (9300)
  • RIM BlackBerry Torch (9800)
  • RIM BlackBerry Bold (9700)
  • RIM BlackBerry Curve (9360)
  • RIM BlackBerry Bold (9780)
  • RIM BlackBerry Bold (9790)
  • HUAWEI Ascend Y330
  • HTC Desire 320a (0PF1100)
  • Motorola Charm (MB502)
  • Motorola Defy (MB525)
  • Motorola Key (EX225)
  • Motorola Milestone (A853)
  • Nokia 3710
  • Nokia E71
  • Nokia E72
  • Sonim XP5560
  • Sonim XP5560IS

Re: GPS Time Reset Issue Impacting Location Accuracy on Select Phones

I got a text from PM that my phone is one of the models affected by this problem. How does PM know what model phone I have? I now have a Motorola G4 Play, but did have a Blackberry Curve 9360 when I first signed up with PM last year. Does the IMEI come into play here?

Public Mobile knows the model of your phone by IMEI.  They know it as soon as you connect to the network, and also know any time you switch to a different device.

 

 

I'm looking at the list of some of the affected devices, and some of those are 10+ years old.  I know that in the case of the Nokia E71, those generations of Symbian phones had next to a useless GPS chipset anyways, often taking minutes to get a GPS lock even if you were under a clear sky.  I do wonder how accurate cell phone tower triangulation is, but it clearly wouldn't be as accurate as the device's internal GPS.

Ok, Thanks. Since my Motorola G4 Play isn’t on the list Moderator Brooke wrote, do you think the PM text I received is going off the IMEI from my original Blackberry Curve?

How does Speakout do it then? Since you have to provide an IMEI from the account that can apparently be different from the phone itself?

And then...isn't it curious that the OP got the text but the phone he has now isn't on the list.

Who knows what Speakout is doing.  They could be using an IMEI that is manually typed in for all we know.  It could be the first IMEI to connect to the network, or there could just be a long delay.  All I can tell you is that when the phone connects to the network, the carrier knows the IMEI. Whether Rogers is sharing that information with Speakout is a different story.  This is the very reason that IMEI should be avoided for number porting from most carriers, although I realize that Speakout requires it.

If you look at the list of affected devices, I don't see the Moto G Play as having anything in common with the others, and it has a fairly recent Qualcomm Snapdragon chipset when compared to everything mentioned in the affected device list.  I'm almost certain that your Moto G4 Play is fine.  It's kind of like when there's a car recall and the manufactuers send recall notices to everyone registered to have purchased a model, even though they know that many of the vehicles are no longer in use, or have been sold/traded-in/upgraded.

Good explanation. Thanks Folks for your time.

@z10user4 

This is false

 

The second your cell phone registers on the Speakout network (place a call or send a txt) you now need to provide that new IMEI in order to port the number

 

@computergeek541 

That is why many people fail port with Speakout

They try using older IMEI after upgrade

(Which is backwards from many networks, eg Bell/Solo/Virgin who always has original IMEI hardcoded on account of device you purchased/upgraded. They can SEE new IMEI but require OLD IMEI to port)

 

No idea if Telus brands follow Rogers but I strongly suspect they would be more like Bell since they copy them in most things

I agree with what would seem to be a properly technical way to do it. But it seems that people struggle with porting from Speakout and apparently, from what I understand, this is due to needing to use the IMEI on file and not necessarily the current device.

But I'm just going on what I think I've gathered from this place...not personal experience.

I'm open to it all being wrong. You don't need to be quite so harsh.

Do you have actual personal experience porting from Speakout after changing devices while there?
