Vodafone India — Balance over

Address:

Udaipur, Rajasthan

i use a dual sim phone and use my internet on my gujarat vodafone no.
but it has happened many a times that suddenly my internet starts being used from the other rajasthan vodafone no. and my balance gets over. i dnt see my phone or change any settings and this happens a lot of time. and even when the balnce gets over my settings o[censored]sing internet is on the gujarat no. only then how come it consumes internet from the other sim.
and even before almost months back when i had one sim phone only that time also suddenly on roaming when i dnt even call or pic any call my balance used to get 0.
my rajasthan no. is [protected]
