Well, i have decided to part ways with my stubborness and move on from glo? And that means new sim and number..
But i cant just throw my sim away because (emails, social networks,banks,work,family etc) i also need to have a more private number.


I just need three choices to pick from. (All must use a micro/nano sim. Preferably micro) wanted to get the new 3310. But it uses a mini sim (the biggest one), the phone should be portable as well because ill be carrying it with my main phone


Choice 1. Very cheap phone. Just for calls the kind you'd give your grandma

Choice 2. Cheap phone. Possible a very previous version of android, windows,blackberry os 7 below..may run whatsapp and other modern apps

Choice 3. 2015/16/17 budget phone. You should know what i mean here. The 3310 is an example



Please give me your opinions



Update- [s]i am considering the blackberry 9790. Its cheap at 6k[/s] The sim is too big
I may consider a used phone
