ZTE Velocity (MF923)
I was told by my SIM card provider that a SIM card could have a slow connection.... My device is ZTE Velocity (MF923)
Has something changed here, in contrast to 2019. We did not have the impression that there was a slow connection here then....
According to the AT&T homepage, the device can still be used after 3G is discontinued in February 2022.
I don't know what to do at the moment - buy the SIM card, or a new, more up-to-date device?
Here is the link to the SIM-Card I would like to buy - see also attachment.
Here is the pdf that shows, that my device still can be used.
see page 9 bottom right
Or would you recommend ordering the SIM card directly in the US - and if so, where?
Thanks for your help and best regards.
