if your plan is DSL plan, Globe will be providing you a wired telset. they have cordless telset but I think it has extra charge for the telset.
Your friend might be using LTE Plan thus they have this Wireless phone called SuperHome Phone which they can carry around and use as landline..
if you really want to have a Wireless phone called Super Home Phone, you need to change your service from DSL to LTE plan. you need to call 211 or (02) 730-1000 for the said request. note that your landline number will change if you will change from DSL to LTE.
now if you wanted to stick on DSL plan and have the wired telset, call 211 or (02) 730-1000 using any Globe mobile phone to have you account checked and request for onsite repair.
