Mobile data / dual sim router weirdness appreciate help
Discussion
Appreciate any help this is driving me mad!
I have a teltonkia rut-901 dual sim router.
When I put my o2 sim in the unit I can access my Amazon aws Aurora MySQL database.
When I put my ee sim in, 3 of my 5 applications fail to even acquire their schema, even though the connection file is identical to the 2 working ones and internet speed / antenna gain etc is actually better than the o2 card.
If I take the ee card out of the router and put it into my iPhone and tether the computer, all the apps work perfectly.
I’ve messed with trying to open port 3306 but it just won’t have it. Maybe I’m doing it wrong? Any ideas out there?

Ee are very aggressive about forcing as much traffic as possible over ipv6 instead of ipv4, when in many cases it isnt appropriate and causes problems with anything more than the basic donkey web/social app browsing. Try turning off ipv6 in as many places as you can on your router.
I am guessing when you are tethering from your phone, the wifi hotspot on your phone isnt routing the ipv6 traffic forcing everything through ipv4.
How are you connecting to your database? Hostname? Dyndns? Fixed ip? When i host servers I can sometimes avoid the problems with clients on ee having problems by making sure my dyndns entries resolve to the ipv4 address only, i remove the ipv6 entry. Happens most often when hosting a server on sky broadband and trying to connect from ee and taking the ipv6 address out the dyndns updater fixes it.
Port forwarding wont help as all the carriers except 3 force you onto CGNAT all the time unless you pay them a fortune for a fixed ip sim, with 3 you can usually get a proper routable net facing 188.x.x.x ip by changing apn.
Unfortunately 3s customer support is dogs
t and in many areas their network is over congested.

My initial thoughts are IPv6 too... But it could be the 'rut 901' making a hash of NATing (ee like to use IPv6 for the end points).
Have a look at the what the computer thinks it has as a connection, v4 vs v6, DNS, routing etc and see if you can get any clues from both types of ee connection.
Keep us posted.
