So I'm trying to make some little radio phone thing but I need a good RF module that is strong and has high tolerance to interference. I heard LoRa is good for arduinos but i dont know which module best suits me. Im just looking for something that is strong, easily accessible, and can last me a bit. My application/goal is to be able to send messages between two arduinos
Range?
Which bands are you interested in?
You mention ‘phone’, are you planning to transmit & receive audio?
What codec / quality and bitrates are you considering?
These will help you choose a processor and suitable radio link.
If it’s just mono voice quality, your easiest go to might be a cellular modem shield that has all tha audio on board, all you need to do is set up the call / answer as appropriate.
Or you could preprocess the voice, and push it as 3G/4G data…
Any thoughts?
Some details of what your actual use application is would help us .......
On a general point, a UNO is not the best choice for using LoRa devices. The UNO is 5V logic level, the LoRa devices are 3.3V. There are ways around this problem, but its easier and there is wider choice of LoRa modules if you use 3.3V logic Arduinos.

Pay attention to the 3V3 vs Arduino Uno 5V fact.
If you don't want to solder that module on your own pcb, consider to use an all in one module like the Lora Radio Node. There are several other options available.
