i have a sim card from a foreign country i have had for a while in a low end samsung a13 phone. working fine roaming, data, etc all okay.
however when I put the sim on a pixel6 or a pixel8a the sim doesn't connect.
both the pixel and the samsung come from the same country. and by looking at the specs on gsm arena both phones support the same frequencies for 2g, 3g, 4g with the pixel supporting far more than samsung.
i borrowed another old samsung phone an a20e and the card works but not on the pixels? is there a way to troubleshoot why the card is not connecting. the operator obviously doesn't help.
the card is from a latam country the Samsung and the pixels are European versions
