So with all the ZTE bans coming in, does this have band 20?
Oh right, this must be fake news, not. Sent from my South Korean phone.
Oh dear, national security risk for using equipment made by manufacturers from another county? What a flipping joke. What equipment exactly does this country produce? Are American/Japanese/Germany/Korean parts or equipment used? BTW, haven't you heard there is an economic war going on right now between US and China?
Nor scaremongering at all - the BBC story linked to is factual. It also clearly explained what the national security risks were. As for the security of your mobile phone, you are free to trust a company to treat you fairly and honestly, even though it breached international sanctions then lied to the regulatory authorities about the corrective actions it would take. I choose not to. And CA was nothing to do with spyware, you do know that, right? And the information that was collected was agreed to under their Facebook settings, you know that too, right?
