Internet connection

Hello Musee, We understand your problem with HSDPA Universal Modem. Normally, the Modem usually stops working after a long time. Meanwhile, regarding its inability to connect with Airtel Network it could be coming from the momentary nonavailability of the Airtel Internet service which is usual when using Airtel internet service as well as some other networks. You can try using the Airtel Sim-card after sometime. Thank you for asking your question in EngineeringAll.com/question/
