We can clearly see that 136 people are facing the same problem plus a dozen more that didn't complaint yet but are about to. Apple need to come up with an update and get this sorted please ASAP.

No news yet but I was able to get a new eSIM installed from the Verizon App's chat support. Just quickly type in representative and get to a human and tell them that Apple suggested a new eSIM. Process takes a bit of time but way better to do at home than at a strip mall store. I won't be able to do the walking test until tomorrow though. I'm not too hopeful however based on a recent comment from someone else. At least I can say I did all the things at this point.

I buy I phone 15 pro max ,noticed signal issues then I gave mobile to customer care there is an issue with the mobile after submitting the report to xcite,they replace mobile with same model,the newly received mobile also same signal issues,but xcite refused to return the product this time,some of the technicians told me this may be because its dual sim and dual sim model made for china,that’s why signal issues coming,I contacted apple service also many times no positive help I get, Iwas really disappointed and sell the mobile,after that I purchase 14pro max Middle East version the mobile also have same signal issues, now I bought one router and now I am using mobile with WiFi connection,at the same locations Iam using Samsun and Oppo both have full network

This lack of service isn’t a carrier issue, it’s an iPhone update issue in my case. Since the new update, communication with non-iPhone/non iCloud users has been miserable, and this was not the case prior to the recent update. The service in general seems similar, except with non-iCloud users. I can barely send a text anymore it sucks and Apple needs to recognize this is not a made up issue, it’s a problem….NOT A CARRIER PROBLEM quit pawning blame.

Do you know if this would work on connection issues with an iPhone 13 (which use physical SIMs but mine has ESIM)? Apple suggested that Verizon remove the SIM card and replace it with ESIm, so I think I only have an eSIM now (which didn’t fix the problem, Apple also cleared out the software and had me start from new, which didn’t work either).


And if it could work, my carrier would need to do it, correct? Thanks.

I used a prepaid card from the same carrier i usually have. i did not fully deactivate the second e-SIM but switched the reception of it off.

Never change a running system. I have no idea if the phone falls back into a malfunction if i would fully remove the prepaid e-SIM which is now in my phone. Does that answer you question?

A side effect of this operation is, that the 5G and 4G reception is not only more stable it's remarkably stronger than ever before, even stronger than in my iPhone 13 Pro MAX.

By the way: I was again in the apple store today , and they confirmed that they made a bug-report to the software development. It may be that they fix the problem with one of the next IoS releases.

I’ve been having issues with my iPhone 15 pro max pretty much from day one. I’m with Vodafone and was getting dropped connections and poor reception with phone only using 3G in strong 5G areas on occasions. I’ve spent last four weeks trying to resolve it with different methods including the network resets blah blah. The eSIM swap definitely changed the symptoms but still poorer connectivity.


yesterday I went to Trafford Apple and they reported the RF band had failed their testing equipment. I bought the phone from John Lewis and they are refusing to give me a new phone and want to repair it. They’ve quoted 20 days but said should be less.


im just peeved that a phone that’s barely four weeks old is getting treated like a device that’s 14 months old. I’m in the process of fighting it as ive also got a bizarre charging issues but spent that long in Apple Store that I came away with at least one issue resolved.

I have an iPhone 14 Plus with Verizon and ESim only. Yesterday I had T-Mobile put a second eSIM in with a month of prepaid.


calling my usual phone #, at first I thought it worked, but then one call failed at the end of the day (failed for me means the call goes straight to VM and doesn’t show in missed calls). I’ll try again today.
