Glo network Arrgh!!! sorry, sis.
I'm not using Glo but I also experienced issues accessing peakd recently but I found a way.
My sister had once had this issue, I can't remember how she said she sorted it out.
I guess for the main time, you can continue subscribing on the Airtel line and keep connecting it to the other device via WIFI.
