879041 - Phone connectivity disabled when on Wifi and using an UMTS-only carrier.

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: Hardware, defect)

Description

[Hubert Figuiere [:hub]]

I put my Koodo SIM card into an Inari device. The phone at the back says UMTS 850/1900 which is what is needed for Koodo / Telus. The network is found.

I couldn't receive calls or SMS.

This is with the 1.0.1 builds that came with it and updated from today OTA.

I rebooted the phone again and I received the SMS.

But I still can't call.

Following this, without rebooting I tried to get to receive another SMS from the same sender and I couldn't get it. Call was sent directly to voice mail as well. Not notification on the phone.

And then I lost network.

I believe the problem might be this:

When I'm connected to wifi it seems that the phone get off the network. It started working when I left the house... This also would explain why I received the SMS on reboot (before it go on the wifi) but then didn't work afterwards...

It should be noted that my carrier, like almost all but one in Canada only have UMTS. No GSM.

I'll do other test later when I swap the SIM card again. (I only have one, it is my main phone)

I did the test this morning.

First I encountered bug 882159 which is bad.

I enabled Wifi.

Asked somebody to send me a SMS. Didn't get it.

Disabled Wifi. When the phone managed to get back on the network, I received the SMS.

This is a blocker for dogfooding. Can't use that phone at all.

It is with the OTA that comes from inari/1.0.1/nightly channel.

And to outline how bad it is, let me summarize the situation in Canada.

We have 3 nation wide telco that share 2 networks. One of the network is GSM + UMTS in the 850/1900 bands, Rogers. The other that is shared by 2 of the telcos (Bell and Telus) is UMTS only in the 850/1900 bands (they opened it in November 2009 so that they could have iPhone and get a slice of the oligopolistic marketshare)

To add icing in the cake, the smaller "new carriers" operate UMTS only in the AWS (1700 MHz) band. No GSM either - but this is irrelevant here as we don't have an AWS capable phone.

So this bug actually prevent most Canadian to dogfood FxOS properly.

Hi Hubert, can you please provide the ril log to us. By the way, I am not sure if dogfood supports 850 band.

Comment 7

[Hubert Figuiere [:hub]]

How can I get these RIL log?

The sticker under the battery (the one with the IMEI) says "UMTS 850/1900/2100". If it doesn't support UMTS 850, then the sticker is a lie.

The problem DO NOT occur on a Geekphone Keon GP-002(fx)
