If the phone is still sending data through your home line with roaming switched off, or through no line at all, WhatsApp has no connection to use.</p> <aside class="verdict"> <p class="verdict__head">The short answer</p> Check four things in this order: the eSIM is turned on, it is selected for mobile data, data roaming is on for it, and the plan still has data and days left. A verification code is a separate problem. WhatsApp sends it by SMS to your home number, and a data-only eSIM cannot receive SMS. </aside> <h2 id="check-which-line-carries-your-data">Check which line carries your data</h2> <p>If WhatsApp works on wifi and stops as soon as you leave it, check these settings first.</p>https://heyatli.com/blog/iphone-18-sim-tray/Thu, 10 Sep 2026 03:30:00 -0700https://heyatli.com/blog/iphone-18-sim-tray/<p>The iPhone 18 Pro and iPhone 18 Pro Max have no SIM tray when bought in the United States, Canada, Mexico, Japan or the six Gulf states, and a nano SIM slot everywhere else. The iPhone Duo, the foldable Apple announced on the same day, has no tray in any market.</p> <aside class="verdict"> <p class="verdict__head">The short answer</p> Bought in the United States, Canada, Mexico, Japan or one of the six Gulf states, the iPhone 18 Pro is eSIM only. Bought anywhere else, it keeps a nano SIM slot, and in mainland China it takes two nano SIM cards. The iPhone Duo and the iPhone Air are eSIM only everywhere. On a phone with no tray, the SIM card sold at an airport counter is not an option, so a local rate means an eSIM. </aside> <h2 id="what-apple-announced">What Apple announced</h2> <p>Apple announced three phones on 9 September 2026, in press releases for <a href="https://www.apple.com/newsroom/2026/09/apple-debuts-iphone-18-pro-and-iphone-18-pro-max/">iPhone 18 Pro</a> and <a href="https://www.apple.com/newsroom/2026/09/apple-unveils-iphone-duo/">iPhone Duo</a>.</p>https://heyatli.com/blog/dual-sim-travel/Sun, 21 Jun 2026 16:13:00 -0700https://heyatli.com/blog/dual-sim-travel/<p>Most phones sold in the last few years can run two lines at once. That is what makes a travel eSIM worth having: your own number stays reachable while a second line carries the data at local prices, and you never choose between the two.</p> <aside class="verdict"> <p class="verdict__head">The short answer</p> Install a travel eSIM alongside your usual SIM, make the eSIM your data line, and turn data roaming off for the home SIM and on for the eSIM. Calls and texts stay on your number, the internet runs on the eSIM, and the home line cannot generate a data bill. One catch: keeping the home line active is not automatically free. Receiving a text can carry a charge on some plans, so check yours before you rely on it. </aside> <h2 id="who-does-what">Who does what</h2> <p>Your home SIM handles your number, incoming calls, incoming texts and bank verification codes. The travel eSIM handles all mobile data: maps, messaging, browsing and calls made over WhatsApp or Telegram.</p>
