Increases in the prices of goods in a 1:1 fashion with income, especially staples? Creating a dominate telco market where having a phone is necessary (and therefore phone prices will be disproportionately higher?)? These are just some reasonable non-catastrophist concerns, which I'm sure there are a number of.
> Increases in the prices of goods in a 1:1 fashion with income
For locally produced goods should be fine because producers are poor too.
For imported goods it might be harmful because UBI cash could get sucked back out of the poor region really quickly. What I'm hoping is that sucking cash out with imports will correlate with increased volume (that it won't be 1:1 exactly) of imports of useful equipment that is not manufactured locally.

Don't they already use phones for small banking like money transfers?
