If you need help, service for your Firefox OS device, or if an app developer is unable to assist with your support request, please contact the carrier who you purchased it from.
Bangladeshi Operator Grameenphone launched Firefox OS in Bangladesh. It is a joint venture enterprise between Telenor and Grameen Telecom Corporation. I have added all the information from the below sources
I am proposing the OEM (Intex and Spice) information here. Because in India, Mozilla partnered with Hardware manufacture Intex and Spice and did not partnered with any operators. So, rather adding operators information, its better to add the Hardware manufactures contact information.
I just made a revision.
Thanks, Safwan, for your revision. I think the new format looks much better.
Swarnava, thanks for adding the information for India. This will help lots of people.
A million thanks to both of you!
