Sim Card for TP-Link TL-MR6400

PeedieLass — Mon, 27 Feb 2023 16:57:48 GMT

Hi. I have recently bought a TP-Link 4G LTE Router and a EE 5GB data Sim card. I have successfully activated the Sim card. We can connect to the router, but there is 'no internet connection' . Can anyone help? Have we got the wrong SIM card?

@PeedieLass : Any SIM should work.

That router is able to send SMS. What does texting AL to 150 from it fully report verbatim (it is free)?

It should work try visiting add-on.ee.co.uk to check the status of the sim card.

Your issue is either with:

You don't have any data allowance nor credit to buy some with.
The APN/Profile settings are not suitable for EE.

I have kept that router's User Guide open in the hope that you would come back & request further "How to" details.

Hello XRaySpeX. I hope you might be able to help.

I also have a TL-MR6400 4G router and would like to know if this will do what I need with an EE SIM (I have not purchased it yet). I would like to use what it calls "Virtual Servers" essentially NAT so that I can access a local computer/service (e.g. on port 80 and port 22) [local=connected to the router] externally (e.g. when I am not at home, not connected to the router, i.e. from anywhere on the internet). The router will allow this, if and only if the network (EE) allocates a public IP address to the SIM connection to EE (not necessarily static as I can always setup a dynamic dns). Do you know if EE does this? or what alternatives there are to connect to my local network from outside? I have a camera connected to the network which I use to monitor things. The camera is effectively a web server. I am also planning to use a Raspberry Pie (to which I can connect via ssh) to control some things at home remotely.

Many thanks in advance for any help. I have tried other networks eg. Smarty, Tesco but they are "virtual" and only allocate private IP addresses.

I am new on this system and I am not sure if my reply/question to XRaySpeX got through, so here it is again just in case:

@velastin : No, you won't be able to. You will find yourself up against a limitation of EE's mobile network. The EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT, which games consoles often object to, which means you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB.

If this occurs there is nowt you can do to avoid it. IMHO Mobile BB is not suitable for running servers.

Many thanks for the info. It is frustrating, but such is life...
