Hello Sterling,
Thanks and I appreciate your resourceful response. However, I’m afraid you misunderstood my question. Although the reply is resourceful, my question was different. The global model A2411 (if I’m not wrong stating that. As A2411 is the model for many countries) is supported by some home networks of their countries and lack 39GHz and 29GHz support which is available in the A2342 (The US model).
So here is a paraphrase of my initial question.
If I purchase an iPhone 12 Pro Max (when they release it) and try to use in India, the phone should work fine as it includes the bands available in India. However, if a phone bought in India will not provide the experience that the US model gives. Am I right?
