Any where in the world you can find places to buy physical phone cards to call back your home or office for business calls. Phone cards are one of the cheapest ways to make international calls rather than using your mobile phone through the roaming program. International roaming is good as you have to just cal the number which is within your mobile phone. The problem is once you reach home you may be shocked to see the heavy mobile phone bill for that month due to the roaming call charges. So it is better to use any kind of International calling cards that can give you peace of mind after finishing the International call or the overseas call as there will be no roaming bill waiting for you in your home. When using a physical calling card there are ways to insert the second calling card if you are going to continue with the call when the money or the calling minutes is going to be over or if you want to make another call using the calling card.. This will help you to continue with the call with out keying your card number. Just follow the calling card providers’ instruction. One provider says like this” After finishing the call, press # # twice to cut the line or the make a follow- on call”. Another one says “Press the # key and hold it for about 2 seconds after you finish with the first call. You will hear a voice prompt to guide you through the next call”. This Follow on Call service is Free.
