I will be going to the UK for the month of May. I have a Nexus 5 and would like to use the Google Navigation feature over there (uses lots of data). I see that you can buy a 30 day plan from local carriers cheaply. Can I just remove my Koodo SIM and use the local SIM for the month, and then reinsert the Koodo SIM on my return? Will there be any problems at either end (I know the local networks there are freq. compatible)? I understand all Nexus 5 Phones are unlocked even though I currently have a Tab with Koodo.
