If you are concerned about bandwidth and data usage from Friendship Lamps when using a mobile hotspot, don't worry! They use very little.
We at Filimin ran a test to answer this using a dozen Friendship Lamps. The lamps were automatically touched 18 times a day. The data showed that they varied in bandwidth usage from 200kb in a day to 300kb in a day.
That comes out to be (at most) 9000 kb in a month. So, regardless of your Internet plan, you shouldn't see any significant change in Internet performance or your monthly bill. For comparison, in one month, one Friendship Lamp touched 18x/day will have used the equivalent of less than 20 seconds of a high-definition video on YouTube.
