Cellular Network connection not available

linjennifer — Wed, 05 Jan 2022 07:29:10 GMT

Hello!

I just activated my sim card and got the 40$ plan (4.5gb 3g speed). My phone is a Xiami Redmi pro 4 (China). The phone is supposedly compatible according to their website. I have try to configurate the APN settings still with no luck. I am wondering if there is something i am missing or not doing properly? Or is the phone simply doesn't work with PM?

I would really appreciate your help,

Thank you 🙂

Check your APN against this site

@linjennifer APN only affects data. Are you able to make calls and send texts?

I am having trouble finding specs for that specific model but some Asian-market (and European market) phones don't work with Public Mobile (nor Koodo, Telus, Bell, Virgin, Lucky Mobile). Can you confirm that the phone includes both 850MHz and 1900MHz 3G network?

Corrected

I think Redmi 4 Pro Chinese version means Redmi 4 High-Spec. According to the official page in Chinese...

GSM B2/B3/B5/B8
WCDMA B1/B2/B5/B8
TD-SCDMA B34/B39
CDMA2000/1X BC0
FDD-LTE B1/B3/ B7
TD-LTE B38/B39/B40/B41(2555-2655MHz)

PM uses Band 4 (1700/2100) and 13 (700) for LTE and Band 2 (1900) and 5 (850) for UMTS. So it will support 3G but it will NOT support 4G.

Refer to this question on Zhihu (Also Chinese) on Mi 6.

PM uses Band 4 (1700/2100) and 13 (700) for LTE and Band 2 (1900) and 5 (850) for UMTS. So unfortunately, you'll need to buy a new phone.

@austinhuang NO--if your spec list for the phone is correct, this phone is fine for calls, texts, and HSPA+ speed data since it supports B2 and B5 WCDMA (aka 3G UMTS with HSPA/HSPA+ data).

@linjennifer I believe this phone should be compatible. Could it be locked to a provider back in China? I don't know if mobile providers in China typically carrier-lock a phone or not. You could also try a network reset (try searching in the settings) or factory reset to see if it resolves the issue. Do note that a factory reset will wipe your phone so make sure you first back up anything you want to keep and isn't already backed up or synced to a cloud-based service.

@austinhuang,

Public Mobile uses many more bands than that for LTE. See here:

https://productioncommunity.publicmobile.ca/t5/Discussions/LTE-network-fundamentals/m-p/134356#M58227

Her phone should support 3G just fine and 4G Band 7 only, assuming the specs provided are accurate.

@linjennifer, if it's a dual SIM phone, can you try putting the SIM in another slot. Sometimes it makes a difference.

It's more a Hz thing. I'm just choosing the closest bands.

4G doesn't work on my old Huawei Honor 5 (Chinese ver, not 5X) even though it supports like 1 band. 3G doesn't work either.

Thank you everyone for your help! It turns out there was a problem with my activation. My phone number was used by 2 customers? I will accept as solution the first person who said the phone was compatible 🙂
