Or no phone at all. I didnt have a phone before i decided to flee lifelong welfare dependency due to severe disabilities and heavy beurocracy in germany by taking 500€ and flying to paraguay without speaking a word of spanish and without a plan other than to #LifeFreeOrDie - best choice ever, as much as i may be struggling to pay rent and medicine espacially this month but still, i do at least have my paraguayan ID and am more or less in the process of getting my taxnumber which will open me some more doors.
When traveling (or generally in such a place as this where theres sometimes 12 hour long power outages... Rare, but still) a phone is pretty useful though.
