Tracfone BLU View 5G Smartphone w/ 1-Yr Service (Unlimited Talk / Text & 24GB) Expired

1. To harvest the plan from the phone, you just go to tracfone.com/activate and follow the instruction, make sure to choose "activating new phone" and then "Keep my own number" and follow the procedure. After everything is done, make sure the transfer is completed and the plan is activated (check by texting balance to 611611, on the app and on the website) then move on to transfer the number back to your current phone (suggested to be done on the day after your first transfer).
Using the same method, go to tracfone activating website, this time choose "bring my device" (note: you can do it by buying a BYOD kit which costs $1 at Target and similar places or using eSim) and, again, follow the instruction.
*big notice: when transfer this unlimited plan to another unlocked phone, the plan may acts weirdly and not display correctly as Unlimited plan, that's when you need to contact customer support to ask them to fix it for you.

2. Probably: this phone < A53 < pixel 6A. It's full name is Blu View Speed so you can go look it up on Google.

3. The Unlimited Plans CANNOT stack. What happens when you activate another Unlimited Plan on top of the current one is the current plan will be terminated and the new plan will be activated immediately. However, you can still keep the data and service duration.
Example: You activate plan 1, then a month later, you activate plan 2 on top of plan 1. The total service duration (which does not guarantee call/text/data) will still be extended by 1 year, make it 2 years total BUT the plan duration is still 1 year, counting from when you activate the 2nd plan. The remaining data still carries over.

Always $20 off. I've been a new customer for years
