The Nokia 215 phone costs $28 and goes on sale in Europe, the Middle East, Africa, and Asia in the first few months of 2015.

OK it does not have a lot of features and is an entry-level phone at the lowest cost possible. However it is jolly useful if you travels a lot or lives somewhere where recharging is tricky.

It proves that batteries can be made to last longer than a day and that phones can hold power for an extended period of time. iPhone users are constantly moaning how quickly their phones drain, but then iPhone users are pretty draining themselves.

The phone runs on Nokia Series 30+ software. It has dual SIM cards, so people can operate with two functioning numbers simultaneously. Using a single SIM, the battery will keep going on standby for 29 days; the second SIM option can last 21, with up to 20 hours of talk time, 50 hours of MP3 listening, and 45 hours of listening to the phone's built-in FM radio.

It has got a web connection although it is not 3G but it does have Bing search, the Opera Mini browser, MSN Weather, Twitter, and Facebook. They will not run fast, but what do you expect for $28.
In fact we were surprised that it has a VGA camera and a 32MB micro SD card, a torch, and comes in bright green, black and white.
