Will not connect to data

[tos1]

I have a samsung galaxy a12, model sm-a127f/ds with 128gb storage. I had no data when I purchased the phone a few years ago. Six months ago I added data to the phone from my Canadian mobility provider. Since then I could not get connected to data. Everything else works, text, talk and wifi. I've tried everything under the sun including getting the provider to try to figure it out, but no luck. I was told it is an international phone because the model ends with a /ds and it's not compatible with a Canadian provider. Can anyone shed some light on this issue. Thanks

The Canadian GSM Bands are, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band.

Since 2021, Canadian Carriers no longer use the 2G network, and 3G networks are slowly being shutdown. 

But it looks like your International device doesn't use the Bands supported by the Canadian Carriers.

Oh great! I have it set to 2g/3g and lte. I don't think the phone gets lte as well. Thanks for letting me know.

Hi tos1,

It seems there is a compatibility issue with your international Samsung Galaxy A12 (model SM-A127F/DS) with the network bands used by your Canadian mobility provider.

Canadian carriers primarily use specific LTE (4G) and 5G bands. If your phone doesn't support these bands, it might struggle to connect to mobile data.

Thank you for providing the required information RedDogRabbit.

Thanks for your response. I should be more careful choosing a phone.

Especially if you get one from Amazon or Ebay.. I've seen lots of International variants being sold there.. US version isn't too bad, as you can always manually Flash the Canadian Firmware, and most importantly the CSC, which you can't do with the International Exynos variant.

Lesson learned, you get what you pay for at those places.
