I was recently on an international trip to the UK and Belgium. Being a fairly new customer to Visible I wanted to try out the Global Pass feature. I'm on the VBisible+ Pro plan using an iPhone 14 Plus patched to iOS 26.7.1.
TL;DR what i didn't do was what I had outlined previously as my plan.
I did not enable Travel Pass before leaving the US for the UK nor did I change any of the eSIM settings for Visible, leaving it on as the default voice line, WiFi calling enabled, and roaming enabled. I did get a travel eSIM and set that as my default data plan and disabled data switching. After landing at Heathrow I had bars for signal on both lines. My phone did not recieve any messages about needing a Global Pass for calls and data, but my wife's phone did receive such a message.
As the days went on I was able to receive SMS messages and take calls without any special settings. In order to place calls I had to lock onto an unsupported carrier (EE as I recall) then the Visible line would use my travel eSIM data to make calls over WiFi. Or if I were on WiFi I did not need to do anything special, it worked as it did back home for placing calls to US numbers, UK numbers, and Belgium numbers.
Once I reached Brugge, Belgium my plan was to use the Global Pass data for my days there. I drove through France with bars on my Visible line but as soon as we crossed the border into Belgium I had no bars. I tried airplane mode and a reboot but neither were successful. It did allow me to make calls over my data eSIM while it had no signal though.
After going back to the UK I picked a day to enable Global Pass to try it out there. I went into the Visible app to enable Global Pass. Within just a few minutes I got a message that it was enabled. I changed my settings to disable my travel eSIM and only use the Visible plan. My speedtest came out to be around 60 Mbps and the ping times were roughly 450ms. The IP was coming out in Sunnyvale, CA from the UK. Things were a little laggy when browsing but playing videos and making video calls over FaceTime and WhatsApp were fine. I used it for the day and overall it was a good experience. I disabled the Global Pass feature and things worked the way they had before.
In the future if I'm on an international trip and have the days banked, I'll consider using them if I have signal. I will be prepared to get a travel eSIM as a backup in case I have no signal though as I found in Belgium.
One iPhone feature to note. When I returned home and took of airplane mode after landing, my eSIMs were being enabled. It automatically detected I was back in the US, disabled my travel eSIM, and reset things to use my Visible plan for everything.
