After insert different operator sim, and then insert regular sim then solved.
But, New problem is after replace ZTE MC801A with GL-X3000, my all 3 tapo devices not connected with internet always show orange light.
and if i replace back to GL-X3000 with ZTE then all tapo device working fine with green light.
- tapo device not connected with internet if use GL-X3000 instead of ZTE MC801A with same sim. no any internet issue with mobiles, desktop, tv working fine with GL-X3000 internet.
Why tapo devices not working with GL-X3000?
