Samsung Flip Phones

I have a samsung flip style phone due to i work for the govorment we are not allowed smart phones in the ship yard alto this has a camra i was able to cover that with proxy,My question is ,This phone only holds so many text messages , i need away to reroute my messages to a nother Ntelos phone so i can save them/view them as im always recieving unwelcomed messages from numbers i dont know ,almost to many to hold and view and lock them in to take some action, also i use to be able to see my entire call log and incoming and out going texting numbers/contacts. what happend with that service, i know its pre paid but we all still should be able to have these options, other local pre pay companies like verizon and teen mobile has these options now where Ntelostook them away, ive been a customer sence Ntelos was formaly sun com- altell -prime co, so please dont make some of your best customers go to another company over options we want/ need in some cases like myself ! Thank you!
