Iv had my phone from ID for over a year now.. personal phone used as back up for work as i work out and about and need good internet connection . These last 4 ish months iv noticed my signal keeps dropping.. Keeps showing H+ on my phone, so rather poor. But before the period I was very happy with the service.. I did see about that time the THREE the carrier network were having issues so i left if a few months to see if it would be resolved.
Iv got the Huawei P smart. I try rebooting, turning data on a off.. occasionally works..
