Hi All, I hope you can help with a UMobile Data SIM problem I'm having.
I've been using a UMobile Data SIM in a (no brand) 4g Router for several months and it worked fine. Last week the old router died and I bought a new TP-Link MR200 LTE Router. This router has a SIM slot.
When I inserted the UMobile SIM it would not connect to the mobile network.
I looked through all the possible config options, tried some, but still no connection. This is the same SIM that worked perfectly in the old router just days ago.
I figured maybe the new router is faulty.
So I took the SIM card from my mobile phone (Digi network) and tried that in the new router. Worked straight away!
I put the UMobile SIM in my mobile phone - it worked right away (allowed personal hotspot allowed connections from all devices).
So - new the router works (with a Digi SIM).
The UMobile SIM works (with mobile phone, data mode).
But the UMobile SIM refuses to work in the router.
I've dug deeper and tried selecting network Band manually (1,3,7,8), also tried dropping the router to accept 3G only. Upgraded the Router Firmware - nothing works.
Anybody seen this before? Any suggestions?
Happen to me too. Check tplink forum which states because using new 5G simcard. cannot be used on old tplink archer mr600 (v1)
