Maybe trying out on wifi can be very hard. This means your signal is low or maybe a little bit hectic you can try out on looking for different hot spots and get a better signal in the long run. Maybe considering to put on some work on how they put the best spots for you to work on. I believe that you can get a better signal by making an effort on the rest of the job and taking a lot of things into account where you could get that wifi an upgrade at the very least as well.
Hi Peter. Are you checking if Zoomer Wireless have Wi-Fi calling? If so, at the time of writing, they still don't offer this.
