I got my new iPhone yesterday and had some issues with the Apple transfer only moving the 2 esims from my "Old" 15 Pro Max to the new, 16 PM. The Roamless acount and esim did not attempt to swap, so I contacted them via Chat in their app. They responded in just a few minutes and were very eager to work on the issue. We got the esim installed easily, but my account credits did not post to the new phone account. I finally gave up after about 2 hours of Chat and got some sleep. They were able to set up the account overnight and I am very happy with their perseverance without my input to correct the issue. This morning, I had the full balance and service in place.
So, just a shoutout to Roamless Customer Support for very helpful, prompt attention for an issue. Their rates are a mixed bag since they are far from the cheapest, but do have "Forever" data after purchase and with the current promo it sorts out at $1.96/Gb for US and most Euro service. The promo provides $25 credit for a $20 purchase. I bought it on a whim since I use T-Mobile as my primary carrier in the US and abroad. I also have a US Mobile esim for voice service while roaming, and that esim did not switch to the new phone automatically either. A quick chat with them was all that was needed.
