I am going on a trip to the US at the end of the year, and will be there for a little over a month. Am planning on getting a US sim for calls/texts within the US as well as data, and keeping my Aus sim in it for 2FA texts, etc. I have an Oppo Reno 10x Zoom and both T-Mobile and AT&T suggest my phone is not compatible with their networks when doing an IMEI check. Not quite sure how incompatible they are, but assuming it is terminal enough that I can't reliably use it there.
I am very happy with the Oppo and not planning on replacing it at this stage, so looking for a cheapish dual-sim phone to use while there and then keep as a spare/kids/travel phone afterwards.
Main features I am after would be dual-sim, reasonably large size screen, good speed/memory, and obviously strong compatibility with US phone networks.
Decent camera would be a bonus but not overly fussed as we will have other better phones/cameras. 5G and Samsung (for SmartTag compatibility) would be a bonus as well but not essential.
Budget would be under $300 if possible but can stretch it if there is a good need to. I only paid $500 for the Oppo so not really looking to spend over that on a travel phone.
Any suggestions?
S10?
