Now that our issue is resolved, the product itself is great. We are going to be utilizing it on an upcoming trip out of country so we can communicate if we get separated while doing activities close by. I am excited to try it there. We have tested it locally, and it works like a charm from a pretty decent distance away.
Now let me hopefully provide a troubleshooting trick in case what happened to ours happens to yours. When we first received the goTenna's, we paired them up to two different phones successfully. The way the app tells you to pair it, is by using your phone number. Then goTenna texts you a code, which you then put into your phone and it gets paired up. After we did that and were all set up, we tried to send messages, however only my wife's phone would send and receive. My phone would only receive, but would receive an error when I tried to send any messages. I then tried everything from swapping the antennas to the opposite phone... again only my wife's would send and receive, but I still could only receive but not send. So therefore I knew it wasn't the goTenna's problem, but some miscommunication on our phones and the app. I then tried several other phones from the Iphone 6, 6 Plus, 7, 7 Plus, and a Samsung running android. All the same result. Then after the Noah and their service department were kind enough to swap us for a different pair, we had the same exact problem!
So as a last resort instead of trying to pair the goTenna's using our phone number, we noticed there is a way to do a random ID. So I did that on my phone, and it worked! Using the random generated number instead of my cell number, I was able to send and receive messages on my phone. Ironically, my wife's still would work using her number. So long story short, if you are having problems sending messages using your phone number as the 'ID', try to re-'pair' your goTenna using the generated ID instead of getting one texted. It is a small link under where it asks you to input your phone number! I hope this helps.
I like the idea of goTenna, because:
- we all have smartphones with us anyway (even if there is no signal)
- its only about 2 oz
- seems to have more than enough reach since we are typically all on the same side of the mountain
- can be set to automatically send your location to others in the group on a regular interval
- can be set to automatically respond to a location query from anyone in the group w/o needing to manually respond
- text is many times easier to understand (especially at a distance with outside (wind) noise, than voice over radios
- it provides offline pretty good maps and shows everyone's last updated location relative to each other on the map
- messages sent are confirmed when received within a few seconds, so you know if it the message got through or not
- with shared GPS locations without Cellular coverage, it enables smartphones location sharing similar to Garmin Rhino Radios costing 3-4 times as much.
I have tested goTenna on some hikes and in the wooded/hilly area near my home. I had no problem using it at distances of 1 mile. I have not tried it further yet. Sometimes, I would need to hold the antenna up over my head when there were hills between me and the other goTenna. It's surprising how a few feet of elevation can make a difference. Hanging it from my hiking pole would give even more height, but in testing I have not had to do this yet.
So far we have not fully implemented goTenna as standard equipment, I have been testing it with the group and on my own on a number of hikes. But with recent improvements and anticipated new features to the software, I expect that will change. Right now I have 2 goTennas, and 6 hike organizers. We are not all on every hike, so I need to be there to hand out the other goTenna.
Why have we not gone completely to goTenna over GMRS/FRS?
- Cost is a factor. We really need 2 goTennas per organizer since only one organizer may be on any one hike. If there is only one organizer, then he/she needs to have 2 goTennas to give one to someone else who will help by being "sweep" a the read of the hike.
- Sometimes, voice is better for a quick shout to the other organizer.
GoTenna support, particularly Noah, has been very responsive. After purchasing goTenna, it worked as advertised, but there were features I thought would make it much more useful to me with comms when hiking in a large spread out group in the mountains. goTenna has been very willing to listen and implement some of my suggestions. When I reported issues with the new features, or stability (crashes) of the app, they were quick to respond and within a reasonable time period, fix those issues. They continue to be interested in improving the product with new features today.
