Xperia Z3 not working with SIM

knyaz — Tue, 04 Jan 2022 18:02:14 GMT

Hello everyone,

Have an interesting case here.

My Sony Xperia Z3, that I have purchased recently, doesn't work with PublicMobile SIM card.

Could it be that IMEI number check on PublicMobile website shows it as "Your device has been reported as lost or stolen."

But same check by Canadian Wireless Telecommunications Association on http://www.protectyourdata.ca/en/check-the-status-of-your-device-in-canada/

shows "Your device HAS NOT been reported lost or stolen and is not currently on the national blacklist."

Please help.

Below are the screenshots that are made today.

The public mobile imei checking tool is know to be broken and that is why you won't see users recommending to use that. That is really strange that it shows black listed.

Have you verified that your phone works with other carrier sims like koodo telus or rogers?

Easiest way to check whether you have a phone issue, or not, is to try your SIM in another phone and another active SIM in yours.

What message is on the phone with the PM SIM installed?

Is it the dual SIM model?

Where was it purchased? Has it been used on another network in Canada?

Find the submodel of your phone; there are 1 or 2 models incompatible with Public Mobile.

Sounds as though it is locked to Rogers.

If IMEI check is broken, then I guess this message is not correct either: "Xperia Z3

Your device should work on our Network."

It is not locked. Works with other networks.

You need a Bell/Virgin/Telus/Koodo SIM to test the lock status. Which carrier besides Rogers works in the phone?

The other possibility is you have one of the Z3 models that connects to Rogers 2G network but not PM's 3G; PM has no 2G network.

It has LTE/GSM.

I will check with if it will work with Bell/Virgin/Telus/Koodo. Thank you for suggestion Luddite.

If you reboot your phone with the PM SIM installed what message is displayed on start up?

If you have the dual SIM model try switching the tray.

@knyaz, one generic solution I routinely try is to do a factory reset. Often solves inexplicable/unknown issues for me.

Also, no need to look for and try different carrier sims on your phone. You can easily check your phone's network lock status by entering the service menu:

Punch in *#*#7378423#*#* and then tap on "Service info" and then tap on "Sim Lock"

On the next screen, all 5 items should say "0" if your phone is unlocked. If it says 10 or any number other than 0 beside "Network" then you need to get the phone unlocked before using it with PM.

It is single SIM tray. On reboot it just displays Emergency Services, and I think I saw a quick flash of Public Mobile and it changed to Emergency Services.

Let's wait for an Android afficionado, like @imm1304, but it seems you will need to try a factory reset. Just be sure to back up photos, contacts, etc. so they can be recovered.

Clearly a phone setting issue.

@knyaz, you just confirmed that the phone is unlocked for sure.

Also, the behaviour of brief connection followed by disconnection and "Emergency only" status is consistent with a blacklisted device. Someone had sold me a blacklisted phone off kijiji once a few years ago and thats exactly how it behaved.

Time to send PM the relevant info and screenshots of clean status from the CWTA link to see if PM can correct the database error.

Worst case scenario: someone sold you a lost/stolen device... or the original owner just got around to reporting it to Telus that the phone is lost. PM/Telus system is picking up the blacklisted status slightly earlier than the CWTA if this is the scenario.. I hope this is not what happened to you.

PM does not require the IMEI number to activate an account. So, how do they know a phone is blacklisted?

Re: Xperia Z3 not working with SIM

imm1304 — Fri, 23 Sep 2016 21:37:39 GMT

@Luddite, all north american carriers subscribe to the blacklist. When any device connects to a network, the imei number is reported to the carrier wirelessly and is checked against the database. Thats why the brief connection to PM in this case.

So in @knyaz's case the Rogers network has different data than Public Mobile. Hope it's just a database syncing issue in favour of "not stolen".
