buying unlocked phones from china
I just bought an OPPO find n from china. It is 5g, 4g, LTE. for now it works fine. Tmobile at the store said once it gets rid of 2g network in July those phones would not work anymore. ibut when I asked the seller. They said yes it will. Is this true
There is a lot more to a phones connectivity than just 5G, 4G, LTE, etc. There are specific bands and band combinations that are used for service and those bands can vary based on where you are geographically within the US. T-Mobile is going to require phones to use VoLTE soon. If your device does not support VoLTE or 5G SA and uses the bands needed for those. Then it won't work. Most Chinese phones are not compatible with T-Mobile's WiFi Calling and VoLTE implementation. If you can post your device name and model. I can post a link to what bands it supports.
With 5G, you will only get data on n41 and N66, if the area you are using it in even has those. n41 will more than likely be old Sprint repurposed spectrum. For 4G, it has 2, 4, 12, 41, and 66.
Being a Chinese phone, it more than likely does not support the default (what T-mobile uses) implementation of VoLTE and WiFi Calling. Devices will soon be required to be VoLTE compatible with T-Mobile or cease to work for calling.
I have the Oppo find N foldable phone
here is what the seller sent me.My friend, please check the attachment. It is compatible with tmobile's network. The phone has volte turned on by default. It can be used as long as it shows 4g.
What the seller says, I hope is correct. The only Chinese phones outside of OnePlus that sometimes have working VoLTE that I have personally tried, is my Xiaomi MI MIX 3.
Just as a side note, OPPO and OnePlus are part of the same company.

Yes, but T-Mobile sells OnePlus devices but not Oppo devices.
Thank you so much. I think I will be sending this back

I don't hook up anything for anyone.
