Wrong worng worng.
Andujar5, if you are not sure of what you are talking about then please don't give out worng information.
Codetel, tricom both operate in digital and in analog mode. Now we have new players in the cell market: Centennial and Orange phone. Both Centennial and orange are pure digital.
In my opinion, centennial will give you the best rates in the cell market. If you don't believe me, then check the rates and plans for yourself. If you are concerned about making calls to USA then centennial has the best plan and price / min to call USA. Tricom is also offering a USa calling plan for a cheaper rate but I think the monthly rate is too high.
bring any sprint phone here from USA and have it connected with this company above.
have a nice day.
