Anyone Used Lebara Roaming Add Ons In South America?

Hi
I'm off to Buenos Aires and Rio next week and will need a little data for Uber only. Before I go down the eSim route I wondered if anyone has used Lebara's add ons for these 2 places and if it was any good.
Even if you've not used it in these 2 places is there any reason I should be wary?
Thanks in advance for any replies

Newspapetaxi You can use the roaming rates finder to check you destination and which of the roaming add-ons are available for those locations.

Martin - I know what roaming add ons are available and they appear to be just what I need, however my question is asking if anyone has used them in BA and Rio and if they worked okay.
Thanks

Understood Newspapetaxi! I'll take a look and see if I can find any community members who have used the roaming add-ons and ask them to share their experience with you.

For ayone who may pick this up on a search.
I've just returned from a 16 day trip to Buenos Aires, Iguazu Falls, Rio and Buzios and used two 8 day roaming add ons at £5 each. They worked fantastically in all 4 locations and despite using them quite heavily for Uber and Google Maps for getting around I didn't use more than half of my 1GB allowance both times. I must stress I am not a big user of Facebook, Instagram etc though they can be used when you're back on wifi at your base.
Also worth noting that each add on is actually usuable worldwide, even though you choose a certain country when buying them.
Highly recommended for these locations and cheaper than an esim
