The bar chart illustrates how the number of telephone subscribers in Vietnam changed over the twelve months of 2010, with figures given in millions.
Overall, the number of subscribers increased considerably over the year. Although there were one or two brief periods where growth stalled or dipped slightly, the general trend was strongly upward.
At the start of the year, Vietnam had just over 115 million telephone subscribers. This figure rose modestly during the first few months, though the increase was not perfectly steady, as there was a small decline in March. In April, Vietnam had approximately 124 million telephone subscribers.
