Hi @SimonFear, the Signal Assist unit is excellent, I've had mine for just over 12 months and I've never had a dropped call. If you do decide to buy one it's worth noting that once you have connected it and switched it on, it requires authenticating by BT before it becomes operational. You don't need to do anything yourself but the process can be a few days, it was over a week in my case. Just be prepared for a short delay before you can use it.
Hi Andy, many thanks for the response. This signal Assist unit, is this available to purchase through BT?
