TU Go App Reviews

Good service. I recommend for VIVO clients. It saves me R$30 a day while overseas.

Love it! It allows you to make and receive calls abroad with wi-fi or 3G as if you were home. Also great for when youre in a farm or somewhere with low cellular signal but good enough wi-fi connection. Just didnt five-star it because it sometimes has some sort of issue that makes you miss incoming calls, and also because it just doesnt work eventually. Apart from that, awesome app.

Awesome app

The idea is very good, but unfortunately it doesnt work. When in background it does not work at all. Needs to be redesigned.

It doesnt works properly, im out of the country, i been trying to use but has been impossible, it doesnt works

Its the best app, specially after the last update.

Good app. Would be better if there were a favorites button as on iPhone

Stay in touch, and most definitely the top reason to stay with O2.

A great app for travel. Works just like your phone! Get it today

Being able to make a wifi phone call, without having to pay the Brazilian scorching prices, is very good.

Great roaming tool

Fantastic tool trip

It works perfect, it help me to keep in contact with my family in Colombia while traveling, highly recommend!

It is missing integration with iPhone block calls list, or at least a own way to block calls from specific numbers.

It works perfect. Like having a sim card in the phone!

You need to allow us to block a caller!!! Is a must!!

A free tool to call Colombia and receive calls when traveling.

I am trying to use the app in US. Perfect for SMS texting. However, does NOT ring when people try to call me. Please, fix this major bug. Thanks Now it only works on wifi network. Cannot make calls using 3G/4G network.

Do not work with 3G/4G or LTE, only wifi. Please fix it.

The iOS version isnt working at all on 3G/4G. It only works with wifi... A real shame!
