Hi All,
Vodafone Alcatel U5 is currently on sale for $59 (reduced 40%) at Coles.

I think this is the best budget smartphone currently on the market as it supports all the 3G bands in Australia and very cheap to unlock.
I paid $1.23 to this seller and got the unlock code within 30 minutes and started using my Belong mobile sim.

Alcatel U5 has been even cheaper before @49.50 (https://www.ozbargain.com.au/node/392974), but if you are in a hurry, it's still a good buy at $59.
P.S: According to latest catalog (https://www.ozbargain.com.au/node/407517) the sale is extended until 16/10/2016 (May be they are trying to clear the current stock)
Ok for a grand parent as a first smart phone maybe?
