Xiaomi Redmi phones?

[Bilnok]

Hi, I have a friend of me who I refered to PM, and who is owning a Redmi 9 (International version), but his phone can't detect PM network. But with his iPhone 6 it works. 

Yet, before buying the PM sim card, we checked that all the required frequencies by PM are supported by the Redmi 9 ?

Any solution that can help is welcome. 🙄

Thanks.

Merci beaucoup, ça fonctionne pour mon Xiaomi redmi note 11 pro.

I have had various Xiaomi/Redmi/Poco phones over the years, so I know there is always a problem with the automatic APN settings that have caused my MMS to fail over the years. When I recently switched from my cheap 3G plan to a bigger data plan on 5G, my MMS broke again.

After about an hour of changing APN settings based upon reading a bunch of different support threads from Public Mobile support articles and these forums too, I found the solution ONLY at https://apn.how/ca/public-mobile/xiaomi-redmi-note-12-pro

APN.how shows specific settings per phone model. Since my Redmi Note 11 Pro+ 5G is not listed, I use the exact settings for Redmi Note 12 Pro and MMS now works! These settings include the updated settings people are mentioning for Public Mobile, but what was missing from all these threads that APN.how showed me are the settings for APN Type, MVNO type and MVNO value (both were blank by default on my Redmi phone).

Please see the settings below for the settings that work on my Android based Redmi Note 11 Pro+ 5G, and which will likely works on all other MIUI based phones, and perhaps more Android phones:

This is the protocol to follow if you want to use a "world phone" in Canada - but you need the long name of the phone.  Find the long name of the phone; either listed in "About Phone" section of the "Settings" on the phone OR download the DevCheck app and look at the Hardware section.  Redmi 9 is just the family name, you have to get the specific phone name.  With the phone name go to the FrequencyCheck website and search by device family (Redmi 9) and then pick the specific phone name that you have, there are a choice of 34 individual phone members of the Redmi 9 family.  Once there then then check for Canada/Public Mobile by just following the prompts.

@BilnokJust looking for any variations. Something like settings - about phone.

Adding - it looks like you might have the India version. It has incomplete frequenceis/bands for here.

[Bilnok]

Sorry, what do you mean by full length model? 

In the phone specs area, it is mentinned Redmi 9 only and nothing else.

[dust2dust]

Ah. Winnipeg and Brandon are known trouble spots for Public with marginal phones. Can you supply the full length model.

[Bilnok]

Yes, every step you mentioned has been done, but the phone still does not pick up the PM network. Still, the phone works flawlessly with other providers.

PS: Location Winnipeg, MB.

@BilnokCan the phone be changed to LTE or 4G and the others. Or 3G or WCDMA or UMTS or HSPA and others. Then scan for Public. Also make sure the provider selection is on automatic afterwards.
