Telkom Wireless Phone a Headache

Early this year, a Telkom consultant encouraged me to change my landline telkom phone to the Telkom Fixed Wireless Phones AGP-KW125f. It has been such a painful and frustrating experience. Ten months later and I've hardly managed to make or receive calls. It keeps saying "insufficient funds" or "no sim card". After many calls to Telkom and taking the phone to the store, I return only to find there's another issue. My next trip will be to return the phone and request a landline again or have Telkom keep this dysfunctional phone.
