I am a new expat from USA.
Thankfully, I brought my Vonage box with me, and it works perfectly with a corded phone here. However, I never thought to bring a cordless phone from US, but when I bought a new one here, I find it only has settings for Singapore, Malaysia, or Indonesia. Of course, I have a US phone number, so I am assuming I need a US phone for that reason.
I can request someone to send one, but I have several questions. Will I have trouble with 1) it getting through customs and 2) will it work here with a US Vonage phone number? 3) will I get in trouble doing so? I don't want to break any laws.
