It just so happens I was studying these this morning!
So many of these units (often called GSM Openers) are low-cost Asian rebrands with no direct regard for resell region. Network compatibility is a big factor - so which type of cell network does your selection need to work with?
That aside, many gate operator manufacturers DO NOT recommend GSM units, due mainly to security concerns with random spam dialers inadvertently opening gates. Instead, many offer a BLE or WiFi solution that only works if the user is actually close to the gate, ie 300' or so.
So with that in mind, do you need true 'remote' control through GSM, or do you need so kind of wireless (but local) button to open/close the gate?
Clients wants to eliminate wiring I just found out by email and he claims he researching it. IMO he doesn't have a clue nor do I at this point so I'll send on information from your post. Unfortunately I visited project yesterday, wiring is atrocious and 400" from house to current gate control there is no power. Some underground, some above ground, standard Cat5e and it's not direct burial wire, system control is made by Doorbell Fon.
Brian thanks for info...could you give me some links so I can understand what you researched? He has a phone intercom he wants to eliminate the wiring, is it even possible to transmit voice on a WI-FI and notify your phone system and then open the gate?
He is looking at is the BFT cellular call box with keypad...however as you stated he would have to activate sim card for it to comunicate correct?
Just got off the phone with BFT they said the network unit has better security with a router than cellular? Comes with camera which in my case is a full solution. However real world coverage says 200yards manual says power up and test on phone app "Preditor WiFi" for operation before installation.

I appreciate your help from your last post...this open my eyes, forced my me to look through 28 page manual, enviably I would have screw myself on labor bid.
Dedicated power 20amp is out at gate on GFI... however he says system has backup battery to open gate with remote...funny you mention this... 5000 sq ft house, with no emergency generator, sitting on 30 acres I don't get it?
Why bother with Cellular? Why not just put a small Point to Point (Ubiquity) and call it a day?
Is there line of sight or is it wooded?
Please explain exactly what you are trying to accomplish.
Do you need a new intercom? Do you just need contact closure for release? How do you need to control it? Please answer these questions so that we have a better understanding so that we can help you.
See attach pictures no trees on property excellent line on site...clients want to replace intercom go wireless he wanted cellular and liked the idea of a phone app but not Sim card activation. Currently he has cabling issue between house and gate primarily from improper wire (not direct burial). Also poor conduit installation and I'll bet after looking in structured wiring cabinet wires are spliced in J-boxes .
In place now in a Doorbell Fon Main Controller and Door Strike board to open gate. My research and a phone call I will quote this solution "Predator WIFI Video Intercom" they have their own app. It's most notably suggest you power system up and test Wi-Fi first for signal strength prior to installation. Plus it has a camera built in. This unit is similar to Doorking which Robb has mentioned no experience with either.
There are gate systems that use cellular that are good. I have used this one and it is bullet proof. https://www.youtube.com/watch?v=zpNPCyBOJzw Google is full of them. The video integration is spotty, depending on the vendor.
Here is one that controls the gate with video, no intercom. http://cell-gate.com/
I would also bet that using some configuration of Alarm.com (or like service) would get you where you want to be. This is really a home automation project. They can provide audio, video and remote control over an app, through cellular.
