Digging down power and fiber to a tower is not cheap.
Some metrics to look at
GNI(PPP) Per Capita in Int$ : India - 6,980 / UK - 42,560 / USA - 60,200 [0]
GDP (nominal) per capita in US$ (World Bank) : India - 1,940 / UK - 39.720 / USA - 59,532 [1]
One of those countries, is not like the other two.

It’s about arbitrage. Just quoting some PPP stat from wikipedia is irrelevent and missing the point.
Why do you think PPP is different in different places? It’s not some magic wand you can just wave around.
Yes and it happens regularly. One example :
Apple Music - USA $9.99 per month, UK £9.99 per month, India 1.74 US$ / 1.32 GBP
PPP is only relevent for things that have different prices in different countries (housing, food, etc). There are many things that cost roughly the same wherever you are: oil, macbooks, cell towers, etc.
As a general rule, the easier something is to arbitrage, the less PPP matters. The cost of arbitrage includes transport costs, taxes, and depreciation schedules (vegetables would be cheaper in India vs US because they are hard to transport, for example).
Of course this is only relevent if the US companies aren’t making crazy margins (I don’t personally know, but I suspect it’s possible).
