Toni1953, there ARE service "cards" for this. Walmart sells them in the store and online. As I stated previously, there are many ways you can pay for service aside from buying a card every month.
There is NO bill. This is PREPAID service and you are responsible for making arrangements to pay at least 30-days in advance. Straight Talk will send you reminders by e-mail but will NOT send you a bill as you NEVER owe them anything. This is non-contracted service.
Again, you have the option of going on "Auto-Refill" where Straight Talk will charge your credit card or debit your debit card each month for the next 30-days of service should you choose to elect that option of paying in advance for your service.
You do not buy cards for this. You will receive a monthly bill for its use. You may actually have this in addition to your land line, if desired, or you can use this to replace your land line. This is served by Verizon only. You will need a phone with this. You will have to ask Verizon if you have a specific concern about its viability in your location.
1. Toni1953, the simplest way to look at it is that you have to pay at least 30-days in advance for service. However, there are several ways to avoid having to buy cards every month. The first is to enroll in Straight Talk's "Auto-Refill" where your credit or debit card is charged automatically each month for the next 30-days of service. You do not have to do remember to do anything if choosing this option. Another option is to put service in your "reserve" account. You can put as much service in reserve as you wish. Example, if you want to buy six months worth of service all at once, you can do that ...or seven months, or a year's worth of service, etc.
2. Yes, it is intended to replace your landline home phone service.
3. Yes, it only uses Verizon Wireless voice coverage ...there is no roaming so it is exclusively using Verizon cell towers.
4. Yes, you need to plug a normal home phone into the device. Whatever phone you are using now as your landline phone should work. A cordless system will also work so you can have cordless "extensions" in multiple rooms in the house.
5. Verizon Wireless has good coverage in rural areas so the chances of you being within Verizon Wireless coverage is good. What cell phone carrier do you use? If Verizon, this will use the same tower ...or the nearest tower. You can use the Verizon street-level coverage map to see if you are within the coverage area (copy-and-paste):
After putting in your address, choose the "Prepaid" button as this will show "native" Verizon voice coverage, then click on the "Refresh Map" button. If you are in the purple-shaded area, the Straight Talk Home Phone should work at your location.
